Description

The Intersil HCS193MS is a Radiation Hardened 4-bit binary

UP/DOWN synchronous counter.

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 HCS193MS utilizes advanced CMOS/SOS technology

to achieve high-speed operation. This device is a member of

radiation hardened, high-speed, CMOS/SOS Logic Family.
