Description

The Intersil HCS157MS is a Radiation Hardened quad

2-input multiplexers which select four bits of data from two

sources under the control of a common select input (S). The

Enable input (E NOT) is active low. When the enable pin is

high all of the outputs (1Y-4Y) are forced low regardless of

all other input conditions.

Moving data from two groups of registers to four common

output busses is a common use of these devices. The state

of the Select input determines the particular register from

which the data comes. They can also be used as function

generators.

The HCS157MS utilizes advanced CMOS/SOS technology

to achieve high-speed operation. This device is a member of

radiation hardened, high-speed, CMOS/SOS Logic Family.

The HCS157MS is supplied in a 16 lead Ceramic flat-

pack (K suffix) or a SBDIP Package (D suffix).
