Description and Introduction

8-Bit FET 2.5-V/3.3-V Low-Voltage Bus Switch With 5-V Tolerant Level Shifter The SN74CB3T3245PWR is a high-speed bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 8-bit bus switch  
- **Voltage Supply Range:** 2.3V to 3.6V  
- **On-State Resistance (Ron):** 5Ω (typical)  
- **Bandwidth:** 200MHz  
- **Low Power Consumption:** ICC = 0.5µA (max)  
- **Input/Output Capacitance:** 7pF (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-20  

### **Descriptions:**  
- Provides high-speed switching with minimal propagation delay.  
- Supports bidirectional voltage translation between 2.5V and 3.3V systems.  
- Features an output enable (OE) input for disabling outputs.  

### **Features:**  
- **Fast Switching:** Enables high-speed data transfer.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **Bi-Directional Operation:** Supports data flow in both directions.  
- **5V Tolerant I/Os:** Allows interfacing with 5V logic levels.  
- **ESD Protection:** Exceeds 2000V (HBM) for robustness.  

This information is based on TI's official datasheet for the SN74CB3T3245PWR.

Application Scenarios & Design Considerations

8-Bit FET 2.5-V/3.3-V Low-Voltage Bus Switch With 5-V Tolerant Level Shifter

Alternative Part Number

  • PI3B3245QEX --: Bus switch with similar 8-bit 2-port function and low on-resistance, available in QSOP/TSSOP packages, suitable drop-in for many 3.3V bus-switch applications.
  • CBT3245APW --: 8-bit level-shifting bus switch with 5V tolerant inputs, functionally comparable to the SN74CB3T3245 and commonly used as a cross-reference in TSSOP packages.
  • QS3245SOG --: High-speed CMOS 8-bit bus switch with low propagation delay and TSSOP/SOIC options, a well-known alternative family for CBT-style bus-switch designs.
