Octal D-Type Transparent Latch with 3-STATE Outputs

General Description

Features

These 8-bit registers feature totem-pole 3-STATE outputs

designed specifically for driving highly-capacitive or rela-

tively low-impedance loads. The high-impedance state and

increased 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.

■ Switching specifications at 50 pF

■ Switching specifications guaranteed over full tempera-

ture and V_CCrange

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

■ 3-STATE buffer-type outputs drive bus lines directly

The eight inverting latches of the DM74ALS580A are trans-

parent D-type latches. 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.

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-imped-

ance state the outputs neither load nor drive the bus lines

significantly.

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.
