Presetting the counter to the number on the preset data
inputs (P0 - P3) is accomplished by a low on the asynchro-
nous parallel load input (PL). The counter is incremented on
the low to high transition of the clock-up input (high on the
clock-down), decremented on the low to high transition of
the clock-down input (high on the clock-up). A high level on
the MR input overrides any other input to clear the counter to
zero. The Terminal Count Up goes low half a clock period
before the zero count is reached and returns high at the
maximum count. The Terminal Count Down mode goes low
half a clock period before the maximum count and returns
high at the maximum count.

The HCTS193MS 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 HCTS193MS is supplied in a 16 lead Ceramic
flatpack (K suffix) or a SBDIP Package (D suffix).
