Product Overview
SN74LV4051A_Mux is a Texas Instruments Analog device identified in the datasheet family as SN74LV4051A. Its device function is an 8-channel CMOS analog multiplexer and demultiplexer, using COM as the common output/input and Y0 through Y7 as bidirectional switch terminals. Channel selection is handled by A, B, and C selector inputs, while INH provides enable control.
The device operates over a 1.65 V to 5.5 V VCC range, with recommended supply limits listed as 1 V minimum and 5.5 V maximum. Switch input or output voltage is 0 V to VCC, and logic-control inputs support 0 V to 5.5 V. Analog or digital signals up to 5.5 V peak can be transmitted in either direction.
