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, 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.
? Low Power Dissipation 100 mW Typical
? High-Speed Count Frequency 30 MHz Typical
? Fully Synchronous Operation
? Full Carry Lookahead for Easy Cascading
? Single Up/Down Control Input
? Positive Edge-Trigger Operation
? Input Clamp Diodes Limit High-Speed Termination Effects
