features an internal look-ahead carry and can be used for high-speed
counting. Synchronous operation is provided by having all flip-flops clocked
simultaniously on the positive-going edge of the clock (CP). Outputs (Q
0 to
Q
3) of the counters may be preset to a high or low level. A low level at the
parallel enable input (
PE) disables the counting action and causes the data
at inputs (D
0 to D3) to be loaded into the counter on the positive-going edge
of the clock (provided that the set-up and hold time requirements for
PE are
met). Preset takes place regardless of the levels at the count enable inputs
(CEP and CET). A low level at the master reset input (
MR)setsallfouroutputs
of the flip-flops (Q
0 to Q3) to low level regardless of the levels at CP, PE, CET,
and CEP inputs (thus providing an asynchronous clear function).
The look-ahead carry simplifies serial cascading of the counters. Both
count enable inputs (CEP and CET) must be high to count. The CET input
is fed forward to enable the terminal count output (TC). The TC output thus
enabled will produce a high output pulse of a duration approximately equal
to a high level output of Q
0. This pulse can be used to enable the next
cascaded stage. The maximum clock frequency for the cascaded counters
is determined by the CP to TC propagation delay and CEP to CP set-up time,
according to the following formula:
