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.

DESCRIPTION  
The 74LVQ161 is  
SYNCHRONOUS PRESETTABLE COUNTER  
fabricated with sub-micron silicon gate and  
double-layer metal wiring C MOS technology. It is  
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  
a
low voltage CMOS
