Description  
The Intersil HCS190MS is an asynchronously presettable BCD  
Decade synchronous counter. Presetting the counter to the  
number on the preset data inputs (P0 - P3) is accomplished 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 cascaded 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.
