SN54ACT563 - OCTAL D-TYPE TRANSPARENT LATCHES

Description

The ’ACT563 devices are octal D-type transparent latches with 3-state outputs.

When the latch-enable (LE) input is high, the Q outputs are set to the complements of the data (D) inputs.

SN54ACT563, SN74ACT563 OCTAL D-TYPE TRANSPARENT LATCHES WITH 3-STATE OUTPUTS SCAS550B – NOVEMBER 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 8.5 ns at 5 V D Inputs Are TTL-Voltage Compatible D 3-State Inverted Outputs Drive Bus Lines Directly D Flow-Through Architecture to Optimize PCB Layout description/ordering information The ’ACT563 devices are octal D-type transparent latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs are set to the complements of the data (D) inputs. When LE is taken low, the Q outputs are latched at the inverse logic levels set up at the D inputs. SN54ACT563 . . . J OR W PACKAGE SN74ACT563 . . .
