Description and Introduction

3.3-V ABT Scan Test Devices With 18-Bit Universal Bus Transceivers The SN74LVTH18502APM is a 18-bit universal bus transceiver manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Technology Family:** LVTH (Low-Voltage BiCMOS Technology with 3.3V Tolerant Inputs)  
- **Supply Voltage Range:** 2.7V to 3.6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input/Output Type:** 3.3V Tolerant Inputs, 5V Tolerant I/O (with 3.3V VCC)  
- **Package Type:** 64-pin LQFP (PM)  
- **Logic Type:** Universal Bus Transceiver  
- **Number of Bits:** 18  
- **Output Drive Capability:** ±12mA (Output Current)  
- **Propagation Delay:** Typically 3.5ns (Max 5.5ns at 3.3V)  

### **Descriptions:**  
- The SN74LVTH18502APM is an 18-bit universal bus transceiver designed for asynchronous communication between data buses.  
- It combines D-type latches and D-type flip-flops to allow data flow in transparent, latched, or clocked modes.  
- Supports bidirectional data flow with separate input and output controls.  
- Features 3.3V operation with 5V-tolerant I/Os, making it suitable for mixed-voltage systems.  

### **Features:**  
- **Bus Hold on Data Inputs:** Eliminates the need for external pull-up/pull-down resistors.  
- **Live Insertion/Withdrawal Protection:** Supports hot-swapping applications.  
- **Flow-Through Pinout:** Optimizes PCB layout efficiency.  
- **Power-Up 3-State Outputs:** Prevents bus contention during power-up.  
- **ESD Protection:** Exceeds 2000V per JESD 22-A114.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
