SN54ACT573 - OCTAL D-TYPE TRANSPARENT LATCHES

General Description

These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads.

The devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

SN54ACT573, SN74ACT573 OCTAL D-TYPE TRANSPARENT LATCHES WITH 3-STATE OUTPUTS SCAS538D − OCTOBER 1995 − REVISED OCTOBER 2002 D 4.5-V to 5.5-V VCC Operation D Inputs Accept Voltages to 5.5 V D Max tpd of 9.5 ns at 5 V D Inputs Are TTL-Voltage Compatible description/ordering information These 8-bit latches feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The devices are particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. The eight latches are D-type transparent latches. When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the logic levels set up at the D inputs. SN54ACT573 . . .
