BINARY COUNTER WITH ASYNCHRONOUS CLEAR
General Description
These (synchronous presettable up) counters are monolithic complementary MOS (CMOS)
integrated circuits constructed with N- and P-channel enhancement mode transistors. They
feature an internal carry lookahead for fast counting schemes and for cascading packages
without additional gating.
A low level at the load input disables counting and causes the outputs to agree with the
data input after the next positive clock edge. The clear function for the C161 is
asynchronous and a low level at the clear inputs sets all four outputs low regardless of
the state of the clock.
Counting is enabled when both count enable inputs are high. Input T is fed forward to also
enable the carry out. The carry output is a positive pulse with a duration approximately
equal to the positive portion of QA and can be used to enable successive cascaded stages.
Logic transitions at the enable P or T inputs can occur when the clock is high or low.
