74AHC259; 74AHCT259

8-bit addressable latch

Rev. 02 — 15 May 2008

Product data sheet

1. General description

The 74AHC259; 74AHCT259 is a high-speed Si-gate CMOS device and is pin compatible

with Low-power Schottky TTL (LSTTL). It is speciﬁed in compliance with JEDEC standard

No. 7-A.

The 74AHC259; 74AHCT259 is a high-speed 8-bit addressable latch designed for general

purpose storage applications in digital systems. It is a multifunctional device capable of

storing single-line data in eight addressable latches and providing a 3-to-8 decoder and

multiplexer function with active HIGH outputs (Q0 to Q7). It also incorporates an active

LOW common reset (MR) for resetting all latches as well as an active LOW enable input

(LE).

The 74AHC259; 74AHCT259 has four modes of operation:

•

In the addressable latch mode, data on the data line (D) is written into the addressed

latch. The addressed latch will follow the data input with all non-addressed latches

remaining in their previous states.

•

In the memory mode, all latches remain in their previous states and are unaffected by

the data or address inputs.

•

In the 3-to-8 decoding or demultiplexing mode, the addressed output follows the state

of the data input (D) with all other outputs in the LOW state.

•

In the reset mode, all outputs are LOW and unaffected by the address inputs

(A0 to A2) and data input (D).

When operating the 74AHC259; 74AHCT259 as an address latch, changing more than

one bit of the address could impose a transient-wrong address. Therefore, this should

only be done while in the memory mode.

2. Features

Balanced propagation delays

All inputs have Schmitt-trigger actions

Combines demultiplexer and 8-bit latch

Serial-to-parallel capability

Output from each storage bit available

Random (addressable) data entry

Easily expandable

Common reset input

Useful as a 3-to-8 active HIGH decoder

Inputs accept voltages higher than V
