Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74AHC245DWR is an octal bus transceiver manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Technology Family:** AHC (Advanced High-Speed CMOS)  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Channels:** 8 (Octal)  
- **Logic Type:** Transceiver, Non-Inverting  
- **Output Type:** 3-State  
- **Propagation Delay Time:** 7.5 ns (max) at 5 V  
- **Input Capacitance:** 3 pF (typ)  
- **Output Drive Capability:** ±24 mA at 5 V  
- **Package Type:** SOIC (DWR) - 20-pin Wide Body  

### **Descriptions:**
The SN74AHC245DWR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features 3-state outputs for bus-oriented applications and includes direction control (DIR) and output enable (OE) inputs for flexible operation.  

### **Features:**
- **Wide Operating Voltage Range:** 2 V to 5.5 V  
- **High-Speed Operation:** Optimized for low-power and high-speed performance  
- **3-State Outputs:** Allows multiple devices to share a common bus  
- **Bidirectional Data Flow:** Controlled by the DIR (Direction) pin  
- **Output Enable (OE) Input:** Disables outputs when high, reducing power consumption  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation  
- **ESD Protection:** Exceeds 2000 V per JESD 22  

This device is commonly used in data communication systems, bus interfaces, and other applications requiring bidirectional data transfer.
