HD74HC374 Datasheet Octal D-type Flip-flops (with 3-state Outputs)/octal D-type Flip-flops (with Inverted 3-state Outputs)

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD74HC374/HD74HC534 Octal D-type Flip-Flops (with 3-state outputs) Octal D-type Flip-flops (with inverted 3-state.

General Description

These devices are positive edge triggered flip-flops.

The difference between HD74HC374 and HD74HC534 is only that the former is a true outputs and the latter is a false outputs.

Data at the D inputs, meeting the setup and hold time requirements, are transferred to the Q outputs on positive going transitions of the clock (CK) input.

Key Features

  • High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) High Output Current: Fanout of 15 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Output Control L L L H X : Z : L X Clock D H L X X HD74HC374 Q H L No change Z HD74HC534 Q L H No change Z irrelevant off (high-impedance) state of a 3-state output.
