The 74HC4053, 74HCT4053 is a triple single-pole double-throw analog switch (3x SPDT) suitable for use in analog or digital 2:1 multiplexer/demultiplexer applications. Each switch features a digital select input (Sn), two independent inputs/outputs (nY0 and nY1) and a common input/output (nZ). A digital enable input (E) is common to all switches. 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
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
Multiple package options
Specified from -40 ℃ to +85 ℃ and -40 ℃ to +125 ℃
