The SN54/74LS190 is a synchronous UP/DOWN BCD Decade (8421)  
Counter and the SN54/74LS191 is a synchronous UP/DOWN Modulo-16  
Binary Counter. State changes of the counters are synchronous with the  
LOW-to-HIGH transition of the Clock Pulse input.  
LOW POWER SCHOTTKY  
An asynchronous Parallel Load (PL) input overrides counting and loads the  
data present on the P inputs into the flip-flops, which makes it possible to use  
n
the circuits as programmable counters. A Count Enable (CE) input serves as  
the carry/borrow input in multi-stage counters. An Up/Down Count Control  
(U/D) input determines whether a circuit counts up or down. A Terminal Count  
(TC) output and a Ripple Clock (RC) output provide overflow/underflow  
indication and make possible a variety of methods for generating  
carry/borrow signals in multistage counter applications.
