74VHC161  
4-Bit Binary Counter with Asynchronous Clear  
General Description  
Features  
The VHC161 is an advanced high-speed CMOS device  
fabricated with silicon gate CMOS technology. It achieves  
the high-speed operation similar to equivalent Bipolar  
Schottky TTL while maintaining the CMOS low power dissi-  
pation. The VHC161 is a high-speed synchronous modulo-  
16 binary counter. This device is synchronously presettable  
for application in programmable dividers and have two  
types of Count Enable inputs plus a Terminal Count output  
for versatility in forming synchronous multistage counters.  
The VHC161 has an asynchronous Master Reset input that  
overrides all other inputs and forces the outputs LOW. An  
input protection circuit insures that 0V to 7V can be applied  
to the input pins without regard to the supply voltage. This  
device can be used to interface 5V to 3V systems and two  
supply systems such as battery backup. This circuit pre-  
vents device destruction due to mismatched supply and  
input voltages.  
High Speed:  
fMAX = 185 MHz (typ) at TA = 25°C  
Synchronous counting and loading  
High-speed synchronous expansion  
Low power dissipation:  
ICC = 4 µA (max) at TA = 25°C  
High noise immunity: VNIH = VNIL = 28% VCC (min)  
Power down protection provided on all inputs  
Low noise: VOLP = 0.8V (max)
