Description and Introduction

Single FET Bus Switch The SN74CBT1G384DBVR is a single-pole, single-throw (SPST) analog switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** SPST (Single-Pole, Single-Throw)  
- **Number of Channels:** 1  
- **Supply Voltage Range:** 1.8V to 5.5V  
- **On-State Resistance (Ron):** 10Ω (typical at 4.5V)  
- **Low Power Consumption:** 0.1µA (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- Designed for bidirectional analog and digital signal switching.  
- Supports both digital and analog signals (up to VCC).  
- Low power consumption makes it suitable for battery-powered applications.  

### **Features:**  
- **Wide Voltage Range:** Operates from 1.8V to 5.5V.  
- **Low On-State Resistance:** Ensures minimal signal distortion.  
- **Fast Switching:** tON = 5ns (typical), tOFF = 4ns (typical).  
- **Break-Before-Make Switching:** Prevents signal contention.  
- **ESD Protection:** Exceeds 2000V (HBM) per JESD22-A114.  

This switch is commonly used in portable devices, communication systems, and signal routing applications.

Application Scenarios & Design Considerations

Single FET Bus Switch

Alternative Part Number

  • NC7SZ384P5X --: Single-gate bus switch with similar 1-bit switch function in a small SOT-353/SC-70 package, a common cross-reference for the SN74CBT1G384.
  • PI3B3245LE --: Bus switch IC offering comparable signal-switching behavior and low on-resistance, suitable as a functional replacement in similar applications.
  • 74CBTLV1G125GW --: Single 1-bit bus switch from the CBTLV family with similar low-voltage switching characteristics, usable as an alternative with pin/function review.
  • 74LVC1G384GW,125 --: Single-pole single-throw analog switch/bus switch in the LVC family with comparable voltage range and low Ron, offered in TSSOP; widely stocked alternative.
  • SN74LVC1G66DBVR --: Single analog switch from TI's LVC family with similar switching characteristics and the same SOT-23-5 footprint, making it a drop-in style functional substitute.
