Description

The Intersil HCS244MS is a Radiation Hardened Non-

Inverting Octal Buffer/Line Driver, Three-State, with two

active-low output enables.

The HCS244MS 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 HCS244MS is supplied in a 20 lead Ceramic flatpack (K

suffix) or a SBDIP Package (D suffix).
