Description
The Intersil ACS245MS is a Radiation Hardened octal non-inverting
bidirectional bus transceiver intended for two-way asynchronous
communication between data busses.
The ACS245MS 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 ACS245MS is supplied in a 20 lead Ceramic Flatpack (K suffix) or a
Dual-In-Line Ceramic Package (D suffix).
