DM74LS503

8-Bit Successive Approximation Register

(with Expansion Control)

General Description

Features

The DM74LS503 register has an active LOW Enable (E)

input that is used in cascading two or more packages for

longer word lengths. A HIGH signal on E, after a START

operation, forces Q7 HIGH and prevents the device from

accepting serial data. With the E input of an DM74LS503

connected to the CC output of a preceding (more signifi-

cant) device, the DM74LS503 will be inhibited until the pre-

ceding device is filled, causing its CC output to go LOW.

This LOW signal then enables the DM74LS503 to accept

the serial data on subsequent clocks.

■ Performs serial-to-parallel conversion

■ Expansion control for longer words

■ Storage and control for successive approximation A to D

conversion

■ Low power Schottky version of 2503
