16 BINARY SYNCHRONOUS  
BI-DIRECTIONAL COUNTERS  
The SN54/74LS168 and SN54/74LS169 are fully synchronous 4-stage  
up/down counters featuring a preset capability for programmable operation,  
carry lookahead for easy cascading and a U/D input to control the direction  
of counting. The SN54/74LS168 counts in a BCD decade (8, 4, 2, 1)  
sequence, while the SN54/74LS169 operates in a Modulo 16 binary  
sequence. All state changes, whether in counting or parallel loading, are  
initiated by the LOW-to-HIGH transition of the clock.
