Description and Introduction

3.3-V ABT Octal Registered Transceivers With 3-State Outputs The SN74LVTH543PW is a 3.3-V ABT octal registered transceiver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Logic Type:** Octal Registered Transceiver  
- **Supply Voltage (VCC):** 3.3V (2.7V to 3.6V operating range)  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **High-Speed Operation:** 3.5 ns max propagation delay  
- **I/O Compatibility:** 5V Tolerant inputs, LVTTL compatible  
- **Current - Output High, Low:** ±32mA, ±64mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** TSSOP-24  

### **Features:**  
- **Bus Hold on Data Inputs** – Eliminates the need for external pull-up/pull-down resistors  
- **Latch-Up Performance Exceeds 500 mA** – Per JESD 78  
- **ESD Protection** – Exceeds 2000 V per MIL-STD-883, Method 3015  
- **Flow-Through Pinout** – Optimizes PCB layout  
- **3-State Outputs** – Supports bus-oriented applications  
- **Power-Up 3-State** – Prevents bus contention during power-up  

This device is designed for bidirectional data transfer between buses with separate clock and output enable controls for each direction. It is commonly used in data communication, networking, and computing applications.

Application Scenarios & Design Considerations

3.3-V ABT Octal Registered Transceivers With 3-State Outputs

Alternative Part Number

  • 74LVTH543PW --: Same LVTH octal registered transceiver function in the same TSSOP package, offered by NXP as a direct second-source equivalent.
  • 74LVT543PW --: LVT octal registered transceiver with similar 3.3V logic characteristics and pinout, usable where the LVT speed grade is acceptable.
  • 74ABT543APW --: ABT octal registered transceiver in TSSOP with comparable bus-interface function, suitable as a functional substitute when timing margins allow.
