DM74ALS374

Octal 3-STATE D-Type Edge-Triggered Flip-Flop

General Description

Features

This 8-bit register features 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 provides this register 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. It is 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

temperature and V_CCrange

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

■ Functionally and pin-for-pin compatible with LS TTL

counterpart

■ Improved AC performance over DM74LS374 at approxi-

mately half the power

The eight flip-flops of the DM74ALS374 are edge-triggered

D-type flip-flops. On the positive transition of the clock, the

Q outputs will be set to the logic states that were set up at

the D inputs.

■ 3-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 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 flip-flops. That is, the old data can be retained or new

data can be entered even while the outputs are OFF.
