Description and Introduction

OCTAL FET BUS SWITCH The SN74CBT3245ADB is a 8-bit bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 8-bit FET bus switch  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **On-State Resistance (RON):** 5Ω (typical)  
- **Bandwidth:** 200MHz (typical)  
- **Input/Output Capacitance (CI/O):** 10pF (typical)  
- **Propagation Delay:** 0.25ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP (DB) – 24-pin  

### **Descriptions and Features:**  
- Provides high-speed, low-power switching between two ports.  
- Supports bidirectional voltage translation.  
- Features an output enable (OE) input for disabling the switch.  
- Low power consumption (ICC ≈ 0.5μA max).  
- TTL-compatible control inputs.  
- Supports hot insertion.  
- ESD protection exceeds 2000V (HBM) and 200V (MM).  

This device is commonly used in data communication, signal routing, and level shifting applications.

Application Scenarios & Design Considerations

OCTAL FET BUS SWITCH

Alternative Part Number

  • PI3B3245QEX --: Bus switch with similar 8-bit 2:1 mux/demux function and low on-resistance, available in QSOP package, direct functional replacement for the SN74CBT3245A.
  • QS3VH3245Q --: 3.3V high-bandwidth bus switch with comparable 8-bit bus exchange function and low propagation delay, suitable drop-in alternative in QSOP.
  • CBTLV3245APW --: Low-voltage 8-bit bus switch with similar CBT-style architecture and TSSOP package, offering equivalent switching performance for bus isolation applications.
