54F 74F190 Up Down Decade Counter with Preset and Ripple Clock
November 1994
54F 74F190
Up Down Decade Counter with Preset and Ripple Clock
General Description
The 鈥橣190 is a reversible BCD (8421) decade counter fea-
turing synchronous counting and asynchronous presetting
The preset feature allows the 鈥橣190 to be used in program-
mable dividers The Count Enable input the Terminal Count
output and the Ripple Clock output make possible a variety
of methods of implementing multistage counters In the
counting modes state changes are initiated by the rising
edge of the clock
