74HCS574

Octal D-type flip-flop with Schmitt-trigger inputs; positive edge-trigger; 3-state

The 74HCS574 is an 8-bit positive-edge triggered D-type flip-flop with 3-state outputs. The device features a clock (CP) and output enable (OE) inputs. The flip-flops will store the state of their individual D-inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

All inputs are Schmitt-trigger inputs, capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.

Features and benefits

  • Wide supply voltage range from 2.0 V to 6.0 V

  • Schmitt-trigger inputs

  • 3-state non-inverting outputs for bus oriented applications

  • 8-bit positive, edge-triggered register

  • Low power consumption
    • Typical supply current (ICC) of 100 nA
    • Typical input leakage current (II) of ±10 nA
  • ±7.8 mA output drive at 6 V
  • Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
  • Complies with JEDEC standards:
    • JESD7A (2.0 V to 6.0 V)

  • ESD protection:

    • HBM ANSI/ESDA/JEDEC JS-001 class 3A exceeds 4000 V
