74HC4053D,653

The 74HC4053D 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.

• Low ON resistance - 80Ω, 70Ω, 60Ω (typical) at VCC-VEE = 4.5V, 6.0V, 9.0V respectively
• 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
