Description
The Intersil HCTS193MS 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 asynchronous 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 鏗俛tpack
(K suf鏗亁) or a SBDIP Package (D suf鏗亁).
