74LV4051 8-channel analog multiplexer/demultiplexer Rev. 8 16 July 2021 Product data sheet 1. General description The 74LV4051 is an 8-channel analog multiplexer/demultiplexer with three digital select inputs (S0 to S2), an active-LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). It is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC4051 and 74HCT4051. With E LOW, one of the eight switches is selected (low impedance ON-state) by S0 to S2. With E HIGH, all switches are in the high-impedance OFF-state, independent of S0 to S2. V and GND are the supply voltage pins for the digital control inputs (S0 to S2, and E). The V CC CC to GND ranges are 1.0 V to 6.0 V. The analog inputs/outputs (Y0 to Y7, and Z) can swing between V as a positive limit and V as a negative limit. V - V may not exceed 6.0 V. For operation CC EE CC EE as a digital multiplexer/demultiplexer, V is connected to GND (typically ground). EE 2. Features and benefits Optimized for low-voltage applications: 1.0 V to 6.0 V Accepts TTL input levels between V = 2.7 V and V = 3.6 V CC CC Low ON resistance: 145 (typical) at V - V = 2.0 V CC EE 80 (typical) at V - V = 3.0 V CC EE 60 (typical) at V - V = 4.5 V CC EE Logic level translation: To enable 3 V logic to communicate with 3 V analog signals Typical break before make built in ESD protection: HBM JESD22-A114E exceeds 2000 V MM JESD22-A115-A exceeds 200 V Multiple package options Specified from -40 C to +85 C and from -40 C to +125 C 3.
