The TC74VHC 161 and 163 are advanced high speed CMOS  
SYNCHRONOUS PRESETTABLE 4 BIT BINARY COUNTERs  
fabricated with silicon gate C2MOS technology.  
They achieve the high speed operation similar to equivalent  
Bipolar Schottky TTL while maintaining the CMOS low power  
dissipation.  
TC74VHC161FN, TC74VHC163FN  
The CK input is active on the rising edge. Both LOAD and  
CLR inputs are active on low logic level.  
Presetting of each IC’s is synchronous to the rising edge of CK.  
The clear function of the TC74VHC163 is synchronous to CK,  
while the TC74VHC161 are cleared asynchronously.  
Two enable inputs (ENP and ENT) and CARRY OUTPUT are  
provided to enable easy cascading of counters, which facilitates  
easy implementation of n-bit counters without using external  
gates.  
An input protection circuit ensures that 0 to 5.5 V can be  
applied to the input pins without regard to the supply voltage.  
This device can be used to interface 5 V to 3 V systems and two  
supply systems such as battery back up. This circuit prevents  
device destruction due to mismatched supply and input voltages.
