Description
The Intersil HCTS541MS is a Radiation Hardened non-
inverting octal buffer/line driver, three-state outputs. The
output enable pins (OEN1 and OEN2) control the three-state
outputs. If either enable is high the outputs will be in the high
impedance state. For data output both enables (OEN1 and
OEN2) must be low.
The HCTS541MS 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 HCTS54 is supplied in a 20 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).

CAUTION: As with all semiconductors, stress listed under "Absolute Maximum Ratings" may be applied to devices (one at a time) without resulting in permanent
damage. This is a stress rating only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. The conditions listed
