Description and Introduction

Low-Voltage Quad 2-Channel Multiplexer (3-state) with 5-V Tolerant Inputs and Outputs The TC74LCX257F is a quad 2-input multiplexer manufactured by Toshiba. Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Supply Voltage (VCC):** 2.0V to 3.6V (Low-voltage operation)  
- **Input Voltage (VI):** 0V to VCC  
- **Output Voltage (VO):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **High-Speed Operation:** tpd = 4.5 ns (max) at VCC = 3.0V to 3.6V  
- **Low Power Consumption:** ICC = 10 μA (max) at Ta = 25°C  
- **Output Drive Capability:** ±24 mA (min) at VCC = 3.0V  
- **Latch-up Performance:** ±300 mA  
- **ESD Protection:** Exceeds 2000 V (HBM)  

### **Description:**  
The TC74LCX257F is a low-voltage CMOS quad 2-input multiplexer with 3-state outputs. It selects one of two data inputs (A or B) based on the select input (S) and provides the selected data on the output (Y). The output enable (OE) pin controls the 3-state outputs.  

### **Features:**  
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply  
- **High-Speed Performance:** Optimized for 3.3V systems  
- **3-State Outputs:** Allows bus-oriented applications  
- **Power-Down Protection:** Inputs and outputs include pull-up/down resistors  
- **TTL-Compatible Inputs:** Can interface with 5V TTL levels  
- **Packaging:** Available in SOP (Small Outline Package)  

This information is strictly based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Low-Voltage Quad 2-Channel Multiplexer (3-state) with 5-V Tolerant Inputs and Outputs

Alternative Part Number

  • SN74LVC257APW --: Same LVC-family quad 2-to-1 multiplexer with 3-state outputs in TSSOP, pin-compatible and widely available.
  • 74LVC257APW --: Equivalent LVC quad 2-to-1 mux with 3-state outputs in TSSOP package, direct functional replacement.
  • MC74LCX257DT --: LCX-series quad 2-to-1 multiplexer with 3-state outputs, same logic function and similar TSSOP footprint.
  • 74LCX257MTC --: Same LCX-family quad 2-input multiplexer with 3-state outputs in TSSOP, functionally equivalent to the Toshiba part.
