Synchronous Presettable BCD Decade Counters  
General Description  
Features  
Y
Synchronous counting and loading  
The ’LS160 and ’LS162 are high speed synchronous dec-  
ade counters operating in the BCD (8421) sequence. They  
are synchronously presettable for application in programma-  
ble dividers and have two types of Count Enable inputs plus  
a Terminal Count output for versatility in forming synchro-  
nous multistage counters. The ’LS160 has an asynchronous  
Master Reset input that overrides all other inputs and forces  
the outputs LOW. The ’LS162 has a Synchronous Reset  
input that overrides counting and parallel loading and allows  
all outputs to be simultaneously reset on the rising edge of  
the clock.  
Y
High speed synchronous expansion  
Y
Typical count rate of 35 MHz
