SN54AC563 - OCTAL D-TYPE TRANSPARENT LATCHES

Description

The ’AC563 devices are octal D-type transparent latches with 3-state outputs.

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

D 2-V to 6-V VCC Operation D Inputs Accept Voltages to 6 V D Max tpd of 9 ns at 5 V D 3-State Inverting Outputs Drive Bus Lines Directly D Full Parallel Access for Loading D Flow-Through Architecture to Optimize PCB Layout description/ordering information The ’AC563 devices are octal D-type transparent latches with 3-state outputs. When the latch-enable (LE) input is high, the Q outputs follow 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. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly.
