### **Description:**
The TC74LCX157FN is a low-voltage CMOS quad 2-input multiplexer designed for high-speed, low-power operation in 2.0V to 3.6V systems. It selects one of two data inputs (A or B) based on the select input (S) and provides the selected data at the output (Y).
### **Features:**
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply
- **High-Speed Performance:** 5.5ns max propagation delay at 3.3V
- **Low Power Consumption:** ICC = 10μA (Max) at 3.6V
- **5V-Tolerant Inputs:** Allows interfacing with 5V logic
- **Balanced Propagation Delays:** Ensures stable switching
- **Pin-Compatible with 74-Series Logic:** Drop-in replacement for 74HC157 in low-voltage applications
- **Power-Down Protection:** Prevents damage when VCC = 0V
