Description
The Intersil HCS160MS is a Radiation Hardened high speed
presettable BCD decade synchronous counter that features an
asynchronous reset and look-ahead carry logic. Counting and
parallel presetting are accomplished synchronously with the lowto-high transition of the clock. A low level on the synchronous
parallel enable input,
the preset inputs, P0 - P3, to be loaded into the counter. The
counter is reset by a low on the master reset input,
enables, PE and TE are provided for n-bit cascading. TE also
controls the terminal count output, TC. The terminal count output
indicates a maximum count for one clock pulse and is used to
enable the next cascaded stage to count.
SPE, disables counting and allows data at
MR. Two count

NOTES:
1. The TC output is HIGH when TE is HIGH and the counter is at terminal count (HHHH for 161 and HLLH for 160)
2. The HIGH-to-LOW transition of PE or TE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation
3. The LOW-to-HIGH transition of SPE on the 54/74161 and 54/74160 should only occur while CP is high for conventional operation
