SN54HCT273
Overview
These devices are positive-edge-triggered D-type flipflops with a common enable input. The ’HCT273 devices are similar to the ’HCT377 devices, but feature a common clear enable (CLR) input instead of a latched clock.
- Operating voltage range of 4.5 V to 5.5 V
- Outputs can drive up to 10 LSTTL loads
- Low power consumption, 80 µA maximum ICC
- Typical tpd = 12 ns
- ±4 mA output drive at 5 V
- Low input current of 1 µA maximum
- Inputs are TTL-voltage compatible
- Contain eight D-type flip-flops
- Direct clear input
