4-Stage Synchronous Bidirectional Counter
General Description
Features
Y
Asynchronous counting and loading
The ’F169 is a fully synchronous 4-stage up/down counter.
The ’F169 is a modulo-16 binary counter. Features 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.

Functional Description
The ’F169 uses edge-triggered J-K type flip-flops and has
no constraints on changing the control or data input signals
in either state of the clock. The only requirement is that the
various inputs attain the desired state at least a setup time
before the rising edge of the clock and remain valid for the
recommended hold time thereafter. The parallel load opera-
tion takes precedence over other operations, as indicated in
the Mode Select Table. When PE is LOW, the data on the
P –P inputs enters the flip-flops on the next rising edge of
CET is LOW, when a counter reaches zero in the Count
Down mode or reaches 15 for the ’F169 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 de-
rived by decoding the flip-flop states, there exists the possi-
bility of decoding spikes on TC. For this reason the use of
TC as a clock signal is not recommended (see logic equa-
tions below).

the clock. In order for counting to occur, both CEP and CET
must be LOW and PE must be HIGH; the U/D input then
determines the direction of counting. The Terminal Count
