File Number 4619.1
Radiation Hardened Octal Bus
Features
Transceiver, Three-State, Non-Inverting
• QML Class T, Per MIL-PRF-38535
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.

Errors/Bit-Day (Typ)
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.
• 3 Micron Radiation Hardened CMOS SOS
• Fanout (Over Temperature Range)
- Bus Driver Outputs - 15 LSTTL Loads
• Significant Power Reduction Compared to LSTTL ICs
• DC Operating Voltage Range: 4.5V to 5.5V
• LSTTL Input Compatibility
- V = 0.8V Max
