Verification of Logic Gates and De Morgan Theorems using TTL Logic Gates Manufacturer,Supplier and Exporter in India
Product Code : EL-DEECP-1163
Jlab Export is a leading Verification of Logic Gates and De Morgan Theorems using TTL Logic Gates Manufacturer,and suppliers in India
Verification of Logic Gates and De Morgan Theorems using TTL Logic Gates (code EL-DEECP-1163) is a cabinet-type TTL trainer on which students verify gate truth tables and then combine OR, AND and NOT gates to confirm the NOR and NAND functions and De Morgan’s theorems. It offers a 3-input AND gate, NAND, NOR, a 2-input EX-OR and single-input NOT gates, set from four SPDT switches. JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its Ambala works in India.

What Is the TTL Logic Gates and De Morgan Trainer Used For?
The trainer takes students from single gates to simple Boolean proofs. First they record the truth table of each gate — including the EX-OR gate, whose output is 1 only when its two inputs differ. Then they patch an OR or AND gate into a NOT gate to produce NOR and NAND, and finally build both sides of De Morgan’s theorems, (A · B)′ = A′ + B′ and (A + B)′ = A′ · B′, checking that they agree for every input combination. The four SPDT (single-pole, double-throw) switches flip each input cleanly between its two logic levels, and because the ICs sit inside the cabinet with only the sockets exposed, students make every connection at the sockets without handling the chips. It is used in B.Sc. physics and electronics labs, engineering, polytechnic and ITI digital electronics courses, and senior secondary practicals that include logic gates.
Frequently Asked Questions
Which gates are on this trainer?
A 3-input AND gate, a NAND gate, a NOR gate, a 2-input EX-OR gate and single-input NOT gates, all TTL, with the ICs inside the cabinet and connections at sockets.
How are De Morgan’s theorems verified?
By connecting combinations of the OR, AND and NOT gates to build each side of the theorem, then comparing the outputs for all input settings of the four SPDT switches.
How does it differ from the Boolean identities and De Morgan trainer?
This model is listed with TTL gates, SPDT input switches and an EX-OR gate. The Boolean identities trainer, linked below, has printed OR, AND and NOT gates with two red LED output indicators and is aimed at Boolean expressions as well as De Morgan’s theorems.
What is the minimum order and dispatch time?
The minimum order is 10 units, each sold individually, usually dispatched within 7–10 working days after a visual inspection; export transit is added to that.
Who manufactures it?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, at its works in Ambala, Haryana.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd trades as JLab and manufactures digital electronics trainers and laboratory equipment in India; the company was incorporated in 2017 and is based on Hargolal Road, Ambala, Haryana. This TTL logic trainer is produced at JLab’s own works, not bought from a trader, so institutions, dealers and importers buy direct from the factory, each cabinet is visually inspected before it leaves, and repeat orders and spares are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Bhutan in South Asia, Trinidad and Tobago in Central America and the Caribbean, Moldova in Eastern Europe, Guyana in South America and New Zealand in Oceania. The JLab lab tenders page has details for tender buyers.
