Description
The Intersil HCTS7266MS is a Radiation Hardened quad 2-Input
exclusive NOR Gate. A logic level high on either one of the inputs
(A or B) will force the output (y) low. A high on both inputs, or a low
on both inputs will force the output to a logic high.
The HCTS7266MS 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 with TTL
input compatibility.
The HCTS7266MS is supplied in a 14 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
