HCS190MS Datasheet (Intersil Corporation) - Radiation Hardened Synchronous 4-Bit Up/Down Counter

HCS190MS, Radiation Hardened Synchronous 4-Bit Up/Down Counter

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)
