DM74LS503
8-Bit Successive Approximation Register
(with Expansion Control)
General Description
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.
