MC74HC73A
Dual J-K Flip-Flop with
Reset
HighâPerformance SiliconâGate CMOS
The MC74HC73A is identical in pinout to the LS73. The device
inputs are compatible with standard CMOS outputs; with pullup
resistors, they are compatible with LSTTL outputs.
Each flipâflop is negativeâedge clocked and has an activeâlow
asynchronous reset.
The MC74HC73A is identical in function to the HC107, but has a
different pinout.
Features
⢠Output Drive Capability: 10 LSTTL Loads
⢠Outputs Directly Interface to CMOS, NMOS, and TTL
⢠Operating Voltage Range: 2.0 to 6.0 V
⢠Low Input Current: 1.0 mA
⢠High Noise Immunity Characteristic of CMOS Devices
⢠In Compliance with the JEDEC Standard No. 7.0 A Requirements
⢠Chip Complexity: 92 FETs or 23 Equivalent Gates
⢠NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AECâQ100
Qualified and PPAP Capable
⢠These are PbâFree Devices
