How Does It Compare with Other JLab Logic Trainers?
| Trainer | Construction | Power supply | Inputs, outputs and coverage |
|---|---|---|---|
| This trainer (EL-DEECP-1192) | 74 series TTL ICs inside the cabinet; front-panel sockets | 5 V DC, 1 A, short-circuit and overload protected | 10 debounced inputs; 10 red LED outputs; 1 Hz clock; gates through to multiplexers and demultiplexers |
| Logic Gate Circuit Trainer and Digital Computer-II [Bread Board Model] | Breadboard on the front panel; students wire the circuits | 5 V DC, 1 A and ±15 V DC, 150 mA | 10 SPDT inputs with LEDs; 10 output indicators; 1 Hz clock; 3 seven-segment displays |

Choose this trainer for a full digital electronics course on ready-wired ICs, with clean switch inputs and a protected supply. The breadboard model suits labs where students should assemble every circuit themselves, and the logic gates experiment suits an introductory gates-only practical.
What Is the TTL Logic Gate Trainer Used For?
Students patch the sockets on the front panel to the gates and circuits inside, set input levels with the ten logic inputs and read the results on the ten red LEDs. A course typically starts with gate truth tables and Boolean expressions, proves De Morgan’s theorems by showing that both sides of each identity give the same table, builds adders and subtractors, and then moves to sequential logic — flip-flops, counters and shift registers stepped by the 1 Hz clock, slow enough to follow each change by eye — before encoders, decoders, multiplexers and demultiplexers. This is a practical digital electronics trainer kit for B.Sc. physics and electronics, engineering diplomas and ITI electronics trades.
The debounced inputs matter for sequential experiments. A mechanical switch contact bounces as it closes, producing several rapid pulses; a counter driven by an undebounced switch can jump several counts at one press. Debouncing turns each switch movement into one clean transition, so every press gives one clock or one state change. The short-circuit and overload protection guards the 5 V supply against wiring mistakes, which are common when students first patch circuits. Switch off before rewiring and keep patch leads clear of the LEDs and switches.
What to Specify When Ordering
- Experiment list — send your practical manual so JLab can confirm the circuits on the panel match it.
- Patch cords and mains input — patch cords are not mentioned in this listing; ask for them, and give your supply voltage.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
Which experiments does the trainer cover?
Truth tables of TTL logic gates, Boolean expressions, De Morgan’s theorems, adders, subtractors, flip-flops, counters, shift registers, encoders, decoders, multiplexers and demultiplexers, all using 74 series TTL ICs.
What does “debounced logic inputs” mean?
Each of the ten input switches gives one clean logic transition per operation instead of a burst of contact-bounce pulses, so flip-flops and counters respond once per press.
What power supply does it have?
A regulated 5 V DC, 1 A supply with short-circuit and overload protection, which suits TTL ICs and protects the supply against short circuits caused by wiring mistakes.
Do students need to insert ICs?
No. All components and ICs are placed inside the cabinet, and their connections are brought out at sockets on the front panel, so students wire circuits by patching between sockets.
How does it differ from the breadboard model?
Here the ICs are fitted inside the cabinet and the inputs are debounced. On the breadboard model students build each circuit from loose ICs, and it adds a ±15 V supply and seven-segment displays.
What should an export quotation request include?
The quantity, destination country and port or city, delivery terms such as FOB or CIF, your mains voltage, packing or labelling needs and any tender reference.
Who manufactures this trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a digital electronics trainer and laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The TTL logic trainer is built at JLab’s own works rather than bought from a trader, so colleges, institutes, dealers and importers buy direct from the maker, every unit is visually inspected before dispatch, and repeat orders are handled by the same manufacturer. JLab holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise and exports under Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Uruguay in South America, Laos in Southeast Asia, Lesotho in Southern Africa, Uzbekistan in Central Asia and Hong Kong in East Asia. Tender information is on the JLab lab tenders page.
