Octal D-Type TRI-STATE Transparent Latch

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.

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

Switching specifications guaranteed over full tempera-

range

The eight latches of the ALS373 are transparent D-type

latches. While the enable (G) is high the Q outputs will fol-

low the data (D) inputs. When the enable is taken low the

output will be latched at the level of the data that was set

up.

A buffered output control input can be used to place the

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

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