### **Descriptions:**  
The SN74CB3Q3253PWR is a high-speed, low-power, dual 4:1 multiplexer/demultiplexer switch designed for digital and analog signal switching. It provides low on-state resistance and minimal propagation delay, making it suitable for high-speed data routing applications.  

### **Features:**  
- **Low On-State Resistance (5Ω typical)**  
- **Wide Bandwidth (500 MHz typical)**  
- **Supports Mixed-Mode Signal Operation (Digital/Analog)**  
- **Bi-Directional Data Flow**  
- **2.3V to 3.6V Supply Voltage Range**  
- **Low Power Consumption**  
- **Fast Switching (0.25 ns propagation delay)**  
- **TSSOP-16 Package for Space-Constrained Applications**  

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

Application Scenarios & Design Considerations

Dual 1-of-4 FET Multiplexer/Demultiplexer 2.5-V/3.3-V Low-Voltage High-Bandwidth Bus Switch

Alternative Part Number

  • PI3B3253QEX --: Pin-compatible 2:1 dual 4-channel bus switch with similar low on-resistance and TSSOP package, direct functional replacement.
  • CBT3253PW --: Dual 4-channel 2:1 bus switch in TSSOP with matching pinout and logic, widely used as a cross-reference for the SN74CB3Q3253.
  • QS3VH3253Q --: Low-voltage dual 4-channel bus switch with similar switching characteristics and TSSOP footprint, suitable alternative when TI part is unavailable.
  • FST3253MTCX --: Dual 4:1 bus switch offering similar low on-resistance and 3.3V operation as a functional replacement.
