### **Descriptions:**  
The SN74LVC2G157DCUT is a dual 2-to-1 multiplexer that selects one of two data inputs (A or B) based on the select (S) input. It operates over a wide voltage range (1.65V to 5.5V), making it suitable for mixed-voltage applications.  

### **Features:**  
- **Wide Operating Voltage Range:** 1.65V to 5.5V  
- **Low Power Consumption:** ICC = 10 µA (Max)  
- **High-Speed Operation:** 5.1 ns propagation delay at 3.3V  
- **Balanced Propagation Delays:** Ensures signal integrity  
- **I/O Tolerant to 5.5V:** Supports mixed-voltage interfacing  
- **Latch-Up Performance Exceeds 100 mA per JESD 78**  
- **ESD Protection:** Exceeds JESD 22 (2000V HBM, 1000V CDM)  

This device is commonly used in signal routing, data selection, and bus switching applications.

Application Scenarios & Design Considerations

Single 2-Line to 1-Line Data Selector/Multiplexer

Alternative Part Number

  • 74LVC2G157DP-Q100 --: Same 2-input multiplexer function in the LVC family with comparable 1.65-5.5V supply range and pin-compatible logic behavior; automotive-qualified variant available.
  • MC74LCX157DTR2G --: Quad 2-input multiplexer with similar low-voltage CMOS characteristics and TTL-compatible inputs, suitable functional replacement with minor pinout verification.
  • SN74AHC157PWR --: Alternative TI multiplexer from a different logic family (AHC) offering similar multiplexing function and wide supply range, though switching speed and drive differ slightly.
  • NC7SZ157P6X --: Single 2-to-1 multiplexer with similar LVC-compatible logic levels and small package, suitable for space-constrained designs.
  • 74LVC1G157GW --: Single 2-to-1 multiplexer in LVC logic family offering equivalent switching behavior and wide supply voltage range.
