BCD DECADE/MODULO 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, whil
