Description
The Intersil HCS245MS is a Radiation Hardened Non-Invert-
ing Octal Bidirectional Bus Transceiver, Three-State,
intended for two-way asynchronous communication between
data busses. The HCS245MS 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.
The HCS245MS utilizes advanced CMOS/SOS technology
to achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family.
The HCS245MS is supplied in a 20 lead Weld Seal Ceramic
flatpack (K suffix) or a Weld Seal Ceramic Dual-In-Line
Package (D suffix).

To prevent excess currents in the High-Z (Isolation)
modes, all I/O terminals should be terminated with 10kΩ
to 1MΩ resistors.
