IN74HC112A
IN74HC112A is Dual J-K Negative-Edge-Triggered Flip-Flop manufactured by IK Semiconductor.
TECHNICAL DATA
Dual J-K Flip-Flop with Set and Reset
High-Performance Silicon-Gate CMOS
The IN74HC112A is identical in pinout to the LS/ALS112. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALSTTL outputs. Each flip-flop is negative-edge clocked and has active-low asynchronous Set and Reset inputs.
- Outputs Directly Interface to CMOS, NMOS, and TTL
- Operating Voltage Range: 2.0 to 6.0 V
- Low Input Current: 1.0 µA
- High Noise Immunity Characteristic of CMOS Devices
ORDERING INFORMATION IN74HC112AN Plastic IN74HC112AD SOIC TA = -55° to 125° C for all packages
