74HC4051 8-Channel-Mux 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 inputs/outputs (), 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 VCC. Wide analog input voltage range from -5 V to +5 V 7A Low ON resistance: 80 Ω (typical) at VCC-VEE = 4.5 V 70 Ω (typical) at VCC-VEE = 6.0 V 60 Ω (typical) at VCC-VEE = 9.0 V 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 Color: Material: PCB Package Contents: 1 x 8 channel Analog Multiplexer Selector Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
