Description

The

Intersil

HS-3374RH

is

a

radiation

hardened

8-bit

bidirectional level converter designed to interface CMOS logic

levels with TTL logic levels in radiation hardened bus oriented

systems. The HS-3374RH is fabricated using a radiation

hardened EPI-CMOS process and features eight parallel

bidirectional buffer/level converters.

Two control inputs, ENABLE and DISABLE, are used to deter-

mine the direction of data flow, and to set both the in puts and

outputs in the high impedance state. The control inputs may be

driven by either TTL or CMOS logic drivers capable of sinking

one standard TTL load.

The HS-3374RH is a non-inverting version of the industry

standard CD40116. The non-inverting outputs of the

HS-3374RH reduce PC board chip count by eliminating the

need to restore data back to a non-inverted format.
