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).
