CD54HCT251
Description
The ’HC251 and ’HCT251 are 8-channel digital multiplexers with three-state outputs, fabricated with high-speed silicongate CMOS technology. Together with the low power consumption of standard CMOS integrated circuits, they possess the ability to drive 10 LSTTL loads.
Key Features
- Selects one of eight binary data inputs
- Three-state output capability
- True and complement outputs
- Typical (data to output) propagation delay of 14 ns at VCC = 5 V, CL = 15 pF, TA = 25 ℃
- Fanout (over temperature range) - Standard outputs : 10 LSTTL loads - Bus driver outputs : 15 LSTTL loads
- Wide operating temperature range : - 55 ℃ to 125 ℃
- Balanced propagation delay and transition times
- Significant power reduction compared to LSTTL logic ICs
- Alternate source is Philips
- HC types - 2 V to 6 V operation - High noise immunity : NIL = 30 %, NIH = 30% of VCC at VCC = 5 V
