Description
The ’HC74 and ’HCT74 utilize silicon gate CMOS technology to achieve operating speeds equivalent to LSTTL parts. They exhibit the low power consumption of standard CMOS integrated circuits, together with the ability to drive 10 LSTTL loads. This flip-flop has independent DATA, SET, RESET and CLOCK inputs and Q and Q outputs. The logic level present at the data input is transferred to the output during the positive-going transition of the clock pulse. SET and RESET are independent of the clock and are accomplished by a low level at the appropriate input.
Application
- Ultrasound System
- Fans
- Lab Instrumentation
- Vacuum Cleaners
- Video Communications System
- IP Phone: Wired
