The Intersil HCS161MS is a Radiation Hardened 4-Input Binary;
synchronous counter featuring asynchronous reset and lookahead
carry logic. The HCS161 has an active-low master reset to
zero, MR. A low level at the synchronous parallel enable, SPE,
disables counting and allows data at the preset inputs (p0 - p3) to
load the counter. The data is latched to the outputs on the positive
edge of the clock input, CP. The HCS161MS has two count
output, IC. The terminal count output indicates a maximum count
for one clock pulse and is used to enable the next cascaded
stage to count.
The HCS161MS 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 HCS161MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
