FAST AND LS TTL DATA
4-STAGE SYNCHRONOUS
BIDIRECTIONAL COUNTERS
The MC54/74F168 and MC54/74F169 are fully synchronous 4-stage up/
down counters. The F168 is a BCD decade counter; the F169 is a modulo-16
binary counter. Both feature a preset capability for programmable operation,
carry lookahead for easy cascading, and a U/D input to control the direction
of counting. All state changes, whether in counting or parallel loading, are initi-
ated by the LOW-to-HIGH transition of the clock.
