Description and Introduction

LOW-VOLTAGE 16-BIT BUS TRANSCEIVER WITH 5V TOLERANT INPUTS AND OUTPUTS The **TC74LCX16245** is a low-voltage 16-bit bus transceiver manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage (VCC):** 2.0V to 3.6V  
- **High-Speed Operation:** 4.3 ns (max) propagation delay at 3.3V  
- **Output Current:** ±24 mA (at 3.0V)  
- **Input Voltage Levels:**  
  - **High-Level Input Voltage (VIH):** 2.0V (min) at VCC = 2.7V to 3.6V  
  - **Low-Level Input Voltage (VIL):** 0.8V (max) at VCC = 2.7V to 3.6V  
- **Power-Down Protection:** Inputs/outputs include power-off protection  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** TSSOP-48, SSOP-48  

### **Description:**
The **TC74LCX16245** is a bidirectional 16-bit bus transceiver designed for low-voltage (2.0V to 3.6V) applications. It features non-inverting buffers and direction control inputs for data flow management.  

### **Features:**
- **Low-Voltage Operation:** Supports 2.0V to 3.6V power supply  
- **5V-Tolerant Inputs/Outputs:** Allows interfacing with 5V logic levels  
- **Bidirectional Data Flow:** Controlled by **DIR** (direction) and **OE** (output enable) inputs  
- **High Noise Immunity:** Compliant with noise suppression requirements  
- **Power-Off Protection:** Prevents damage when VCC = 0V  
- **Latch-Up Performance:** Exceeds 300 mA per JESD78  

This device is commonly used in **low-voltage digital systems**, **bus interfaces**, and **data communication applications**.
