Handy Digital IC/Memory Tester
Digital
IC Tester for testing TTL / CMOS / DRAM/ Most of the Digital circuits use
74 series TTL, 40/45 series CMOS & 41/44 series DRAM. It is essential
to test the ICs before it is put into the circuit. This Tester is also
useful for servicing/maintenance.
The IC Tester is having 24 Pin ZIF socket for testing the ICs. It has its
own display of 16x1 LCD and own menu for guiding the user. It has the
function of selecting the IC number, Auto Search for unknown ICs, and test
the ICs. Its average search time is less than 0.8 sec.
FEATURES :
Can test 74 Series
TTL.
Can test CD 40/45 Series
CMOS.
Can test 41/44 Series DRAM.
24 Pin ZIF socket for testing ICs.
