Each flip−flop is loaded with a low−to−high transition of the Clock input. Reset is asynchronous and active low.
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 μA
• High Noise Immunity Characteristic of CMOS Devices
• In Compliance with the Requirements Defined by JEDEC Standard No. 7A
• Chip Complexity: 264 FETs or 66 Equivalent Gates
• Pb−Free Packages are Available
