Description and Introduction

OCTAL BUS TRANSCEIVER The TC74ACT245FW is a high-speed CMOS octal bus transceiver manufactured by Toshiba. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Family:** ACT (Advanced CMOS Technology)  
- **Supply Voltage Range (VCC):** 4.5V to 5.5V  
- **Input Voltage Range (VI):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (IOH/IOL):** ±24mA  
- **Propagation Delay (tpd):** 6.5ns (max) at 5V  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The TC74ACT245FW is an octal bidirectional transceiver with 3-state outputs.  
- It is designed for asynchronous communication between data buses.  
- Direction control (DIR) determines data flow (A to B or B to A).  
- Output Enable (OE) disables outputs when high, allowing bus isolation.  

### **Features:**  
- **High-Speed Operation:** Compatible with TTL levels (VIL = 0.8V, VIH = 2.0V).  
- **Bidirectional Data Flow:** Controlled by DIR pin.  
- **3-State Outputs:** Allows bus isolation when OE is high.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **Latch-Up Performance:** Exceeds 300mA per JESD 78.  
- **ESD Protection:** HBM ≥ 2000V, MM ≥ 200V.  

This device is commonly used in bus interface applications requiring bidirectional data transfer.
