Octal D-Type Edge-Triggered Flip-Flops

with 3-STATE Outputs

General Description

Features

■ Switching specifications at 50 pF

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 guaranteed over full tempera-

ture and V_CCrange

■ Advanced oxide-isolated, ion-implanted Schottky TTL

process

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

TTL counterparts

■ Improved AC performance over LS and ALS TTL coun-

terparts

The eight flip-flops of the AS374 are edge-triggered D-type

flip-flops. On the positive transition of the clock, the Q out-

puts 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.
