MOS technology.It is
ideal for low power applications mantaining high
speed operation similar to eqivalent Bipolar
Schottky TTL. It is a 4 bit binary counter with
SynchronousClear.
The circuits have four fundamental modes of
operation, in order of preference: synchronous

and
reset, parallel load, count-up and hold. Four
control inputs, Master Reset (CLEAR), Parallel
Enable Input (LOAD), Count Enable Input (PE)
and Count Enable Carry Input (TE), determine
the mode of operation as shown in the Truth
Table. A LOW signal on CLEAR overrides
counting and parallel loading and allows all
output to go LOW on the next rising
CLOCK. A LOW signal on LOAD overrides
counting and allows information on Parallel Data
Qn inputs to be loaded into the flip-flops on the
next rising edge of CLOCK. With LOAD and
CLEAR, PE and TE permit counting when both
are HIGH. Conversely, a LOW signal on either
PE and TE inhibits counting.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
