Radiation Hardened 8-Bit Bidirectional
CMOS/TTL Level Converter
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
determine 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.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-96786. A “hot-link” is provided
on our homepage for downloading.
