HD74LV4051A
8-channel Analog Multiplexer / Demultiplexer
ADE-205-283 (Z)
1st Edition
April 1999
Description
The HD74LV4051A handles both analog and digital signals, and enables signals of either type with
amplitudes of up to 5.5 V (peak) to be transmitted in either direction (at VCC = 0 V to 5.5 V).
Applications include signal gating, chopping, modulation or demodulation (modem), and signal
multiplexing for analog-to-digital and digital-to-analog conversion systems.
Features
• VCC = 2.0 V to 5.5 V operation
• All inputs VIH (Max.) = 5.5 V (@VCC = 0 V to 5.5 V)
