100344

Low Power 8-Bit Latch with Cut-Off Drivers

The 100344 outputs are designed to drive a doubly termi-

nated 50Ω transmission line (25Ω load impedance). All in-

puts have 50 kΩ pull-down resistors.

General Description

The 100344 contains eight D-type latches, individual inputs

(D_n), outputs (Q_n), a common enable pin (E), latch enable

(LE), and output enable pin (OEN). A Q output follows its D

input when both E and LE are LOW. When either E or LE (or

both) are HIGH, a latch stores the last valid data present on

its D input prior to E or LE going HIGH.

Features

n Cut-off drivers

n Drives 25Ω load

n Low power operation

n 2000V ESD protection

A HIGH on OEN holds the outputs in a cut-off state. The

cut-off state is designed to be more negative than a normal

ECL LOW level. This allows the output emitter-followers to

turn off when the termination supply is −2.0V, presenting a

high impedance to the data bus. This high impedance re-

duces termination power and prevents loss of low state

noise margin when several loads share the bus.

n Voltage compensated operating range −4.2V to −5.7V

n Available to MIL-STD-883
