The 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 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. Benefits: Wide analog input voltage range from -5 V to +5 V Complies with JEDEC standard no. 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 Specified from -40 °C to +85 °C and -40 °C to +125 °C Applications: for Breadboard for for MCU ARM AVR ADC for for PLC RS485 Modbus for Analog acquisition Analog multiplexing and demultiplexing Digital multiplexing and demultiplexing Color: Black Material: PCB Package Contents: 1*8ch Analog Multiplexer 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.
