SN74HCT74D
Overview
The ’HCT74 devices contain two independent D-type positive-edge-triggered flip-flops. A low level at the preset (PRE) or clear (CLR) inputs sets or resets the outputs, regardless of the levels of the other inputs.
- Operating voltage range of 4.5 V to 5.5 V
- Outputs can drive up to 10 LSTTL loads
- Low power consumption, 40-μA max ICC
- Typical tpd = 17 ns
- ±4-mA output drive at 5 V
- Low input current of 1 μA max
- Inputs are TTL-voltage compatible
