How Does It Compare with Other JLab IC Testers?
| Model | ICs covered | Socket or pins | Display and keys | Power |
|---|---|---|---|---|
| This tester (EL-DMI-1032) | 74 series TTL, CD 40/45 series CMOS, 41/44 series DRAM | 24-pin ZIF | 16x1 LCD, 5 function keys | 9 V DC, 250 mA, or 4 x 1.5 V batteries |
| Digital IC Tester | 74 series and 40/45 series digital ICs; more than 300 ICs | 24-pin DIP ZIF | 16x1 LCD, 16 keys | 230 V AC |
| Handy Linear IC Tester | Linear ICs: op amps, comparators, opto devices, regulators, special-function devices, transistor arrays | 8 to 16 test pins | 16 characters in 1 line | 9 V DC, 500 mA adaptor; usable with batteries |
Choose this tester when you need to check DRAM memory chips as well as TTL and CMOS logic, or want a battery-powered unit that moves between benches and service desks. The mains-powered Digital IC Tester suits a fixed station for 74 and 40/45 series logic, and the Handy Linear IC Tester covers analogue chips such as op amps and regulators, which this model does not list.
What Is the Digital IC and Memory Tester Used For?
Most digital circuits are built from 74 series TTL, 40/45 series CMOS and 41/44 series DRAM chips, and a faulty chip can waste hours of fault-finding once it is soldered or plugged into a board. This tester checks each IC first: drop it into the ZIF socket, close the lever, then either key in the IC number from the menu or let the auto-search identify an unmarked or unknown chip. Electronics and computer-hardware labs in engineering colleges, polytechnics and ITI workshops use it to sort stock before digital-electronics practicals, and service and maintenance technicians use it to confirm whether a suspect chip is at fault.
Insert chips with the correct orientation of pin 1, open the ZIF lever before removing them so the pins are not bent, and handle CMOS and memory ICs with care against static discharge. Take the batteries out if the tester will be stored for a long period.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; labs often plan one tester per practical batch plus a service desk unit.
- Your preferred power source — a 9 V DC, 250 mA supply or four 1.5 V batteries.
- Whether you also need a linear IC tester for op amps and regulators, which is a separate model.
Frequently Asked Questions
Which ICs can this tester check?
74 series TTL (listed as 7400 to 741245), CD 40/45 series CMOS (4000 to 40257 and 4501 to 4585) and 41/44 series DRAM (4164 to 414000 and 4464 to 441000). Linear ICs such as op amps are not in its list.
Can it identify an IC with no readable marking?
Yes. The auto-search function looks for unknown ICs, with an average search time of less than 0.8 seconds.
What size of IC fits the socket?
The tester has a 24-pin ZIF socket, so chips up to 24 pins are inserted and released without force on their pins.
How is it powered?
From 9 V DC at 250 mA, or from four 1.5 V batteries, which makes it practical away from a mains socket.
How does it differ from the Digital IC Tester?
Both use a 24-pin ZIF socket and a 16x1 LCD. This handy model adds 41/44 series DRAM memory testing and battery operation; the Digital IC Tester runs from 230 V AC, has 16 keys and is listed for more than 300 ICs of the 74 and 40/45 series.
What should an export enquiry include?
The quantity, destination country and port or city, your preferred delivery terms (for example FOB or CIF), any packing or labelling needs, and the tender reference if one applies.
Who manufactures this tester?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics and digital lab instrument manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The tester is produced at JLab’s own works rather than bought in from a trader, so engineering colleges, polytechnics, dealers and importers order factory-direct, each unit is checked by eye before packing, and repeat orders come from the same manufacturer. The company is registered under CIN U29309HR2017PTC069123 and also holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example Eswatini in Southern Africa, Iceland in Northern Europe, the Philippines in Southeast Asia, Canada in North America and Kyrgyzstan in Central Asia. Tender buyers can refer to the JLab lab tenders page.
