The Intersil ACS541MS is a radiation hardened octal buffer/line driver, with three-state outputs. The output enable pins OE1, OE2 control 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 the 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).
