Radiation Hardened 8-Bit Bus Transceiver
The Intersil HS-82C08RH is a radiation-hardened octal bus
transceiver with three-state outputs. It is manufactured using
a self-aligned, junction isolated CMOS process and is
designed for use with the HS-80C08RH radiation-hardened
microprocessor. The HS-82C08RH allows asynchronous
two-way communication between data buses. The direction
of data flow is determined by the logic level on the
transmit/receive (T/R) input. A logic high on the T/R input
specifies data flow from Port A to Port B of the device.
Conversely, a logic low on the T/R input specifies data flow
from Port B to Port A. The Output Enable input disables both
ports by placing them in the high impedance state.
The HS-82C08RH is ideally suited for a wide variety of
buffering applications in radiation-hardened microcomputer
systems.
