General description

The 74HC/HCT74 is a high-speed Si-gate CMOS device and is pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

The 74HC/HCT74 are dual positive-edge triggered, D-type flip-flops with individual data (D) inputs, clock (CP) inputs, set (SD) and reset (RD) inputs; also complementary Q and Q outputs.

The set and reset are asynchronous active LOW inputs and operate independently of the clock input. Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse. The D inputs must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.

Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.

Features

  • Wide supply voltage range from 2.0 to 6.0 V
  • Symmetrical output impedance
  • High noise immunity
  • Low power dissipation
  • Balanced propagation delays
  • ESD protection:
    HBM EIA/JESD22-A114-A exceeds 2000 V
    MM EIA/JESD22-A115-A exceeds 200 V.
