Description and Introduction

36-Bit Bus Transceivers With 3-State Outputs The SN74ABTH32245 is a 32-bit bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology Family:** ABT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to 85°C  
- **Number of Channels:** 32  
- **Logic Type:** Bus Transceiver  
- **Output Type:** 3-State  
- **Propagation Delay Time (Max):** 4.5 ns  
- **High-Level Output Current:** -32 mA  
- **Low-Level Output Current:** 64 mA  
- **Package Options:** 96-pin TSSOP (DGG)  

### **Descriptions and Features:**  
- **High-Speed Operation:** Optimized for 5V operation with fast switching speeds.  
- **3-State Outputs:** Allows multiple outputs to be connected to a common bus.  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Bi-Directional Interface:** Supports data flow in both directions.  
- **ESD Protection:** Exceeds 2000V per JESD 22 (Human Body Model).  
- **Low Power Consumption:** Designed for reduced power dissipation.  
- **Latch-Up Performance:** Exceeds 500 mA per JESD 17.  

This device is commonly used in applications requiring high-speed data transfer, such as memory interfacing and backplane driving.

Application Scenarios & Design Considerations

36-Bit Bus Transceivers With 3-State Outputs

Alternative Part Number

  • 74ABT32245 --: Same 32-bit ABT bus transceiver function with equivalent 5V ABT technology, offered under the NXP 74ABT series naming.
  • 74ABT16501 --: ABT-family 18-bit universal bus transceiver that can serve similar bus-interface roles where the full 32-bit width is not strictly required.
  • 74ABT16245 --: Widely available 16-bit ABT bus transceiver with compatible signaling; a practical fallback when the 32-bit device is unavailable.
