General Description
These (synchronous presettable up) counters are monolith-
ic complementary MOS (CMOS) integrated circuits con-
structed with N- and P-channel enhancement mode transis-
tors. They feature an internal carry look-ahead for fast
counting schemes and for cascading packages without ad-
ditional gating.
A low level at the load input disables counting and causes
the outputs to agree with the data input after the next posi-
tive clock edge. The clear function for the CD40162B and
CD40163B is synchronous and a low level at the clear input
sets all four outputs low after the next positive clock edge.
The clear function for the CD40160B and CD40161B is
asynchronous and a low level at the clear input 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 Q
A
and can be used to en-
able successive cascaded stages. Logic transitions at the
enable P or T inputs can occur when the clock is high or
low.
