SN54LS169
SN54LS169 is BCD DECADE/MODULO 16 BINARY SYNCHRONOUS BI-DIRECTIONAL COUNTERS manufactured by Motorola Semiconductor.
- Part of the SN54LS168 comparator family.
- Part of the SN54LS168 comparator family.
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...
