Description

The Intersil HCTS540MS is a Radiation Hardened inverting

Octal Buffer/Line Driver, with two active-low output enables.

The output enable pins (OE1 and OE2) control the three-

state outputs. If either enable is high the outputs will be in the

high impedance state. For data output both enables (OE1

and OE2) must be low.

The HCTS540MS 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 HCTS540MS is supplied in a 20 lead Ceramic flatpack

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