Description and Introduction

Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs The TC74VCX245FK is a low-voltage bidirectional bus transceiver manufactured by Toshiba. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range (VCC):** 1.2V to 3.6V  
- **High-Speed Operation:** tpd = 2.5ns (max) at 3.0V to 3.6V  
- **Low Power Consumption:** ICC = 10μA (max) at Ta = 25°C  
- **Output Current:** ±24mA (min) at 3.0V  
- **Input Voltage Range (VI):** 0V to VCC  
- **Operating Temperature Range (Ta):** -40°C to +85°C  
- **Package:** VSSOP-20  

### **Descriptions:**
- The TC74VCX245FK is an 8-bit bidirectional transceiver designed for low-voltage operation.  
- It features non-inverting 3-state outputs for both transmitting and receiving data on a bidirectional bus.  
- Direction control (DIR) and output enable (OE) inputs allow flexible bus management.  

### **Features:**
- **Wide Operating Voltage Range:** Supports 1.2V to 3.6V for compatibility with low-voltage systems.  
- **Bidirectional Data Flow:** Controlled by the DIR input.  
- **3-State Outputs:** High-impedance state when disabled (OE = HIGH).  
- **Power-Down Protection:** Inputs and outputs include pull-up/pull-down resistors to prevent floating conditions.  
- **Latch-Up Performance:** Exceeds 300mA per JESD78.  
- **ESD Protection:** Exceeds 2000V (HBM) and 200V (MM).  

This device is commonly used in low-voltage digital systems requiring bidirectional data transfer, such as portable electronics and communication interfaces.  

(Note: Always refer to the official Toshiba datasheet for the most accurate and detailed specifications.)
