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 radia-
tion hardened, high-speed, CMOS/SOS Logic Family.
The HCS157MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).

CAUTION: As with all semiconductors, stress listed under "Absolute Maximum Ratings" may be applied to devices (one at a time) without resulting in permanent
damage. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. The conditions listed
