DM74AS533 Octal D-Type Transparent

Latch with TRI-STATE Outputs

General Description

These 8-bit registers feature totem-pole TRI-STATE outputs

designed specifically for driving highly-capacitive or relative-

ly low-impedance loads. The high-impedance state and in-

creased high-logic-level drive provide these registers with

the capability of being connected directly to and driving the

bus lines in a bus-organized system without need for inter-

face or pull-up components. They are particularly attractive

for implementing buffer registers, I/O ports, bidirectional

bus drivers, and working registers.

levels) or a high-impedance state. In the high-impedance

state the outputs neither load nor drive the bus lines signifi-

cantly.

The output control does not affect the internal operation of

the latches. That is, the old data can be retained or new

data can be entered even while the outputs are off.

Features

Switching specifications at 50 pF

The eight inverting latches of the AS533 are transparent D-

type latches, meaning that while the enable (G) is high the Q

outputs will follow the complement of the data (D) inputs.

When the enable is taken low the output will be latched at

the complement of the level of the data that was set up.

Switching specifications guaranteed over full tempera-

range

process

TRI-STATE buffer-type outputs drive bus lines directly

A buffered output control input can be used to place the

eight outputs in either a normal logic state (high or low logic
