Overview
The 74HC4053D/AU118, produced by NXP USA Inc., is a triple single-pole double-throw (SPDT) analog switch, designed as a 3x SPDT analog multiplexer/demultiplexer. This component is suitable for both analog and 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 common digital enable input (E) controls all switches, turning them off when set to HIGH. The device includes clamp diodes to protect against voltages exceeding VCC, allowing the use of current limiting resistors for interface protection.
