Description and Introduction

Octal Bus Transceivers With Series Damping Resistors The SN74BCT2245NSR is a 3-state octal bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology:** BCT (BiCMOS)  
- **Voltage Supply Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 6.5ns (max)  
- **High-Level Output Current:** -15mA  
- **Low-Level Output Current:** 64mA  
- **Package Type:** SOIC (20-pin)  

### **Descriptions:**  
- The SN74BCT2245NSR is designed for asynchronous communication between data buses.  
- It features non-inverting outputs and bidirectional data flow controlled by the direction (DIR) input.  
- The output enable (OE) input disables the outputs, placing them in a high-impedance state.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR pin.  
- **3-State Outputs:** Allows bus isolation.  
- **High Drive Capability:** Supports heavy loads.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  
- **Wide Operating Voltage:** 4.5V to 5.5V.  
- **Low Power Consumption:** Optimized for efficiency.  

This device is commonly used in bus interface applications, data transmission, and buffering in digital systems.

Application Scenarios & Design Considerations

Octal Bus Transceivers With Series Damping Resistors

Alternative Part Number

  • 74BCT2245APW --: Same octal bus transceiver function with 25-ohm series damping resistors, different manufacturer and package prefix, suitable drop-in for many designs.
  • CY74FCT2245TQCT --: FCT-series octal transceiver with equivalent 25-ohm output resistors and similar speed, different series naming makes it easy to distinguish.
  • 74ACT2245SC --: ACT-family octal bus transceiver with series resistors, comparable logic function and drive, alternate vendor and series for sourcing flexibility.
  • 74ABT2245D --: ABT octal transceiver with 25-ohm series resistors, a common drop-in functional substitute for BCT2245 when BCT-level input thresholds are not strictly required.
