Description
Functional Diagram
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.
