Description
The Intersil ACTS245MS is a Radiation Hardened octal non-inverting
bidirectional bus transceiver intended for two-way asynchronous communication between data busses.
GND
The ACTS245MS utilizes advanced CMOS/SOS technology to achieve
high-speed operation. This device is a member of a radiation hardened,
high-speed, CMOS/SOS Logic Family.
The ACTS245MS is supplied in a 20 lead Ceramic Flatpack (K suffix) or
a Dual-In-Line Ceramic Package (D suffix).
