... Synchronous Bidirectional Counter General Description The 74F169 is a fully synchronous 4-stage up/down counter. The 74F169 is a modulo-16 binary counter. Fea- tures 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 initiated by the LOW-to- HIGH transition of the clock ...

... The Terminal Count (TC) output is normally HIGH and goes LOW, provided that CET is LOW, when a counter reaches zero in the Count Down mode or reaches 15 for the 74F169 in the Count Up mode. The TC output state is not a function of the Count Enable Parallel (CEP) input level. Since the TC signal is derived by decoding the flip-flop states, there exists the possibility of decoding spikes on TC ...
