Product Overview

The SN74HCT74N is a dual D-type Positive-Edge-Triggered Flip-flop with clear and preset. The HCT74 device contains 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. When PRE\ and CLR\ are inactive (high), data at the data (D) input meeting the setup time requirements are transferred to the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and is not directly related to the rise time of CLK. Following the hold-time interval, data at the D input may be changed without affecting the levels at the outputs.
  • Outputs can drive up to 10 LSTTL loads
  • Inputs are TTL-voltage compatible
  • 40µA Maximum low power consumption
  • 17ns Typical tpd
  • ±4mA Output drive at 5V
  • 1µA Very low input current
  • ±25mA Continuous output current
  • ±50mA Continuous current through VCC or GND
