DESCRIPTION
The 74LVQ163 is a low voltage CMOS
SYNCHRONOUS PRESETTABLE COUNTER
fabricated with sub-micron silicon gate and
double-layer metal wiring C2MOS technology. It is
ideal for low power and low noise 3.3V
applications. It is a 4 bit binary counter with
Synchronous Clear.
The circuit have four fundamental modes of
operation, in order of preference: synchronous
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 outputs to go LOW
on the next rising edge of 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 equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-
ing in the same direction, either HIGH or LOW (tOSLH = |tPLHm - tPLHn|, tOSHL = |tPHLm - tPHLn|)
2) Parameter guaranteed by design
(*) Voltage range is 3.3V ± 0.3V
