DESCRIPTION
The
SYNCHRONOUS PRESETTABLE COUNTER
fabricated with sub-micron silicon gate and
double-layer metal wiring C
ideal for low power and low noise 3.3V
applications. It is a 4 bit binary counter with
Asynchronous 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 (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 sets
all outputs on LOW state. 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.
