74ABT843

9-bit bus interface latch with set and reset

(3-State)

2

1998 Jan 16

853-1620 18864

FEATURES

• High speed parallel latches

• Extra data width for wide address/data paths or buses carrying

parity

• Ideal where high speed, light loading, or increased fan-in are

required with MOS microprocessors

• Slim DIP 300 mil package

• Broadside pinout

• Output capability: +64mA/–32mA

• Latch-up protection exceeds 500mA per Jedec Std 17

• ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

• Power-up 3-State

• Power-up reset

DESCRIPTION

The 74ABT843 Bus interface latch is designed to eliminate the extra

packages required to buffer existing registers and provide extra data

width for wider data/address paths of buses carrying parity.

The 74ABT843 consists of nine D-type latches with 3-State outputs.

In addition to the LE and OE pins, it has a Master Reset (MR) pin

and Preset (PRE) pin. These pins are ideal for parity bus interfacing

in high performance systems. When MR is Low, the outputs are Low

if OE is Low. When MR is High, data can be entered into the latch.

When PRE is Low, the outputs are High, if OE is Low. PRE

overrides MR.
