Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74AHC245DW is an octal bus transceiver manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Technology Family:** AHC (Advanced High-Speed CMOS)  
- **Number of Channels:** 8  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Input Voltage Range:** 0 V to VCC  
- **Output Drive Capability:** ±24 mA at 5 V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DW)  
- **Pin Count:** 20  
- **Direction Control:** DIR pin controls data flow (A to B or B to A)  
- **Output Enable (OE):** Active-low enable for outputs  

### **Descriptions:**  
The SN74AHC245DW is a non-inverting 3-state octal bus transceiver designed for asynchronous communication between data buses. It allows bidirectional data flow controlled by the DIR (Direction) pin and features an output enable (OE) pin to disable outputs when needed.  

### **Features:**  
- **Wide Operating Voltage:** 2 V to 5.5 V  
- **High-Speed Operation:** Optimized for 3.3 V and 5 V systems  
- **Low Power Consumption:** CMOS technology ensures low static power dissipation  
- **3-State Outputs:** Allows bus isolation when disabled  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **ESD Protection:** Exceeds 2000 V per JESD 22  
- **Latch-Up Performance:** Exceeds 250 mA per JESD 78  

This device is commonly used in data communication, buffering, and bus interface applications.
