Radiation Hardened 3-Line to 8-Line
Decoder/Demultiplexer
The Intersil HS-54C138RH is a radiation hardened 3- to
8-line decoder fabricated using a radiation hardened
EPI-CMOS process. It features low power consumption,
high noise immunity, and high speed. Also featured are pin
and function compatibility with the 54LS138 industry
standard part. The HS-54C138RH is ideally suited for high
speed memory chip select address decoding. It is intended
for use with the Intersil HS-80C85RH radiation hardened
microprocessor, but it can also be utilized as a demultiplexer
in any low power rad-hard application.
The HS-54C138RH contains a one of eight binary decoder.
A three bit binary input is used to select and activate each of
the eight outputs, provided the three chip enable inputs are
also present (see truth table).
The HS-54C138RH has an on-chip enable gate. The active
high (G1) and both active low (G2A, G2B) inputs are Anded
together to provide a single enable input to the device. The
use of both active high and active low inputs minimizes the
need for external gates when expanding a system.
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
