Synchronous Presettable BCD Decade Counters
General Description
The 鈥橪S160 and 鈥橪S162 are high speed synchronous dec-
ade counters operating in the BCD (8421) sequence They
are synchronously presettable for application in programma-
ble dividers and have two types of Count Enable inputs plus
a Terminal Count output for versatility in forming synchro-
nous multistage counters The 鈥橪S160 has an asynchronous
Master Reset input that overrides all other inputs and forces
the outputs LOW The 鈥橪S162 has a Synchronous Reset
input that overrides counting and parallel loading and allows
all outputs to be simultaneously reset on the rising edge of
the clock
