Description
The Intersil ACS541MS is a Radiation Hardened Octal Buffer/Line
Driver, with three-state outputs. The output enable pins OE1, OE2 con-
trol the Three-State outputs. If either enable is high the output will be in a
high impedance state. For data output both enables must be low.
The ACS541MS 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 ACS541MS is supplied in a 20 lead Ceramic Flatpack (K suffix) or a
Ceramic Dual-In-Line package (D suffix).
