Description

The Intersil HCTS161AMS high-reliability high-speed presettable
four-bit binary synchronous counter features asynchronous reset
and look-ahead carry logic. The HCTS161AMS has an active-low
master reset to zero,
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
HCTS161AMS has two count enable pins, PE and TE. TE also
controls the terminal count output, TC. The terminal count output
indicates a maximum count for one clock pulse and is used to
enable the next cascaded stage to count.

The HCTS161AMS utilizes advanced CMOS/SOS technology to
achieve high-speed operation. This device is a member of
radiation hardened, high-speed, CMOS/SOS Logic Family.
