Description
The Intersil HCTS191MS is a Radiation Hardened asynchro-
nously presettable 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 asynchronous parallel load
input (PL). Counting occurs when PL is high, Count Enable (CE)
is low, and the Up/Down (U/D) input is either low for up-counting
or high for down-counting. The counter is incremented or decre-
mented synchronously with the low-to-high transition of the clock.
When an overflow or underflow of the counter occurs, the
Terminal Count output (TC), which is low during counting, goes
high and remains high for one clock cycle. This output can be
used for look-ahead carry in high speed cascading. The TC
output also initiates the Ripple Clock output (RC) which, normally
high, goes low and remains low for the low-level portion of the
clock pulse. These counter can be cascaded using the Ripple
Carry output.
The HCTS191MS 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 HCTS191MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
