High–Performance Silicon–Gate CMOS
The MC74HC76 is identical in pinout to the LS76. The device inputs
are compatible with Standard CMOS outputs; with pullup resistors, they
are compatible with LSTTL outputs.
Each flip–flop is negative–edge clocked and has active–low asynchro-
nous Set and Reset inputs.
The HC76 is identical in function to the HC112, but has a different
pinout.
Similar in Function to the LS76 Except When Set and Reset Are
Low Simultaneously
Output Drive Capability: 10 LSTTL Loads
Outputs Directly Interface to CMOS, NMOS and TTL
Operating Voltage Range: 2 to 6V
Low Input Current: 1
μ
A
High Noise Immunity Characteristic of CMOS Devices
In Compliance With the JEDEC Standard No. 7A Requirements
Chip Complexity: 100 FETs or 25 Equivalent Gates

* Both outputs will remain low as long as Set and Reset are low, but the output states are
unpredictable if Set and Reset go high simultaneously.
