MC74HC73A
Dual J-K Flip-Flop with
Reset
High−Performance Silicon−Gate 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 flip−flop is negative−edge clocked and has an active−low
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; AEC−Q100
Qualified and PPAP Capable
• These are Pb−Free Devices
