Bidirectional Operation: Any analog channel (A0-A7) can act as input or output, with COM as the common port.
Break-Before-Make Switching: Prevents signal shorting between channels during switching.
High Noise Immunity: NIL=30%, NIH=30% of VCC (VCC=5V) for stable digital control.
Wide Analog Range: Supports analog signals from VEE to VCC (±5V max).

Usage Guidelines and Precautions

Unused Inputs: All unused control inputs (S0-S2, E) must be tied to VCC or GND to ensure proper operation.
Supply Considerations: Avoid exceeding 0.6V voltage drop across the switch to prevent VCC current draw; VPP_2V5 must be within 2.3-3.47V during operation.
Signal Integrity: Keep analog signal paths short to minimize noise; use proper decoupling capacitors near VCC/GND pins.
Soldering: Follow recommended lead temperature (300°C max for 10s) to avoid package damage.
Thermal Management: Account for θJA=73°C/W when designing for high-temperature automotive environments.
