General description

The 74LVC374A is a high-performance, low-power, low-voltage, Si-gate CMOS device, superior to most advanced CMOS compatible TTL families.

Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation, outputs can handle 5 V. This feature allows the use of these devices as translators in a mixed 3.3 and 5 V environment.

The 74LVC374A is an octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-state outputs for bus-oriented applications. A clock input (CP) and an outputs enable input (OE) are common to all flip-flops.

The eight flip-flops will store the state of their individual D-inputs that meet the set-up and hold times requirements on the LOW-to-HIGH CP transition.

When pin OE is LOW, the contents of the eight flip-flops is available at the outputs. When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does not affect the state of the flip-flops.

The 74LVC374A is functionally identical to the 74LVC574A, but the 74LVC574A has a different pin arrangement.

Features

  • 5 V tolerant inputs/outputs; for interfacing with 5 V logic
  • Wide supply voltage range from 1.2 to 3.6 V
  • Inputs accept voltages up to 5.5 V
  • CMOS low power consumption
  • Direct interface with TTL levels
  • High-impedance when VCC =0 V
  • 8-bit positive edge-triggered register
  • Independent register and 3-state buffer operation
  • Complies with JEDEC standard no. 8-1A
  • ESD protection:
    • HBM EIA/JESD22-A114-A exceeds 2000 V
      MM EIA/JESD22-A115-A exceeds 200 V.
  • Specified from -40 to +85 Cel and -40 to +125 Cel.
