CD74AC151 8-Line to 1-Line Data Selector/Multiplexer
1 Features
- AC types feature 1.5V to 5.5V operation and balanced noise immunity at 30% of the supply voltage
- 8-line to 1-line multiplexers can
perform as:
- Boolean function generators
- Parallel-to-serial converters
- Data source selectors
- Speed of bipolar F, AS, and S, with significantly reduced power consumption balanced propagation delays
- ±24mA output drive current
- Fanout to 15 F devices
- SCR-latchup-resistant CMOS process and circuit design
- Exceeds 2k V ESD protection per MIL-STD-883, method 3015
2 Description
This data selector/multiplexer provides full binary decoding to select one of eight data sources. The strobe (G) input must be at a low logic level to enable the inputs. A high level at the strobe terminal forces the W output high and the Y output low.
