Data Sheet
HCTS245T
July 1999 File Number 4619.1
Radiation Hardened Octal Bus
Transceiver, Three-State, Non-Inverting
Intersil’s Satellite Applications FlowTM (SAF) devices are fully
tested and guaranteed to 100kRAD total dose. These QML
Class T devices are processed to a standard flow intended
to meet the cost and shorter lead-time needs of large
volume satellite manufacturers, while maintaining a high
level of reliability.
The Intersil HCTS245T is a Radiation Hardened Non-
Inverting Octal Bidirectional Bus Transceiver, Three-State,
intended for two-way asynchronous communication between
data busses. The HCTS245T allows data transmission from
the A bus to the B bus or from the B bus to the A bus. The
logic level at the direction input (DIR) determines the data
direction. The output enable input (OE) puts the I/O port in
the high-impedance state when high.
Specifications
Specifications for Rad Hard QML devices are controlled by
the Defense Supply Center in Columbus (DSCC). The SMD
numbers listed below must be used when ordering.
Detailed Electrical Specifications for the HCTS245T are
contained in SMD 5962-95745. A “hot-link” is provided from
our website for downloading.

Intersil’s Quality Management Plan (QM Plan), listing all
Class T screening operations, is also available on our
website.
