HCTS190MS
September 1995
Radiation Hardened
Synchronous 4-Bit Up/Down Counter
Description
The Intersil HCTS190MS is an asynchronously presettable
BCD Decade synchronous counter. Presetting the counter to
the number on the preset data inputs (P0 - P3) is accom-
plished by a low on the 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 decremented
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 cas-
caded using the Ripple Carry output.
If the decade counter is preset to an illegal state or assumes
an illegal state when power is applied, it will return to the
normal sequence in one or two counts
The HCTS190MS 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 HCTS190MS is supplied in a 16 lead Ceramic flatpack
(K suffix) or a SBDIP Package (D suffix).
