STATE DIAGRAM
Inputs can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.

Drive Features for LVC169A:
– High Output Drivers: ±24mA
– Reduced system switching noise
The LVC169A is a presettable synchronous binary counter which
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).
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 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:
