The 74HCT4053D is a triple single-pole double-throw (3x SPDT) Analog Switch 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.

• Logic level translation to enable 5V logic to communicate with ±5V analog signals
• Typical break before make built-in
• Complies with JEDEC standard No. 7A
