74HC4051 74HCT4051 8-channel analog multiplexer/demultiplexer Rev. 10 8 September 2021 Product data sheet 1. General description The 74HC4051 74HCT4051 is a single-pole octal-throw analog switch (SP8T) suitable for use in analog or digital 8:1 multiplexer/demultiplexer applications. The switch features three digital select inputs (S0, S1 and S2), eight independent inputs/outputs (Yn), a common input/output (Z) and a digital enable input (E). When E is HIGH, the switches are turned off. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of V . CC 2. Features and benefits Wide analog input voltage range from -5 V to +5 V CMOS low power dissipation High noise immunity Complies with JEDEC standards JESD8C (2.7 V to 3.6 V) JESD7A (2.0 V to 6.0 V) Latch-up performance exceeds 100 mA per JESD 78 Class II Level B Low ON resistance: 80 (typical) at V - V = 4.5 V CC EE 70 (typical) at V - V = 6.0 V CC EE 60 (typical) at V - V = 9.0 V CC EE Logic level translation: to enable 5 V logic to communicate with 5 V analog signals Typical break before make built-in ESD protection: HBM JESD22-A114F exceeds 2000 V MM JESD22-A115-A exceeds 200 V CDM JESD22-C101E exceeds 1000 V Multiple package options Specified from -40 C to +85 C and -40 C to +125 C 3.
