HD74LVC573A - Octal D-type Transparent Latches with 3-state Outputs

Description

The HD74LVC573A has eight D type latches with three state outputs in a 20 pin package.

When the latch enable input is high, the Q outputs will follow the D inputs.

When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.

Features

  • VCC = 2.0 V to 5.5 V All inputs VIH (Max. ) = 5.5 V (@VCC = 0 V to 5.5 V) All outputs VOUT (Max. ) = 5.5 V (@VCC = 0 V or output off state) Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C) High output current ±24 mA (@VCC = 3.0 V to 5.5 V) Function Table Inputs OC L L L H H: L: X: Z: Q0 : LE H H L X D H L X X Output Q H L Q0 Z High level Low level Immaterial High impeda.

HD74LVC573A Octal D-type Transparent Latches with 3-state Outputs ADE-205-116B(Z) 3rd Edition December 1996 Description The HD74LVC573A has eight D type latches with three state outputs in a 20 pin package. When the latch enable input is high, the Q outputs will follow the D inputs. When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again. When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
