Esi model 1248 digital ic integrated circuit tester
FREE-STANDING DIGITAL IC TESTER PERFORMS A FUNCTIONAL TEST ON ICS WITH UP TO 16 FUNCTIONAL PINS USING 5 VOLT POWER. ALSO TESTS RESISTOR NETWORKS WITH CERTAIN CONFIGURATIONS. TESTS CMOS, TTL, DTL LOGIC, FLIP FLOP, COUNTING CHIPS AND PROBABLY MORE. A BANK OF 16 PROGRAMMING SWITCHES ALLOWS PIN SELECTION FOR POWER, GROUND, INPUTS, CLOCK, NC. A TEST PATTERN GENERATOR RUNS THROUGH TWO TO THE 20th POWER OF INPUT COMBINATIONS AND A COUNTER DISPLAYS THE TOTAL NUMBER OF OUTPUT PULSES, WHICH IS A CHARACTERISTIC NUMBER FOR A GOOD FUNCTIONING DEVICE. A CHART IS PROVIDED FOR SOME COMMON CHIPS AND THE CHARACTERISTIC DISPLAY COUNT CAN BE DETERMINED FOR UNLISTED DEVICES BY TESTING A KNOWN GOOD CHIP. SOCKETS ARE PROVIDED FOR 14 AND 16 PIN DIP CHIPS. TEST TIME IS 1 SECOND FOR TTL, 5 SECONDS FOR CMOS.
