Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74AHC245DBR 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  
- **Package Type:** SSOP (DBR) – 20-pin  
- **Propagation Delay:** 7.5 ns (max) at 5 V  
- **Input/Output Compatibility:** TTL-Level  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
The SN74AHC245DBR is an octal bus transceiver designed for asynchronous two-way communication between data buses. It features 3-state outputs for bus-oriented applications and allows bidirectional data flow controlled by the direction (DIR) input. The output enable (OE) input disables the outputs when high.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **3-State Outputs:** Allows bus isolation  
- **Wide Operating Voltage:** 2 V to 5.5 V  
- **Balanced Propagation Delays**  
- **Low Power Consumption:** Typical ICC of 1 μA  
- **TTL-Compatible Inputs**  
- **ESD Protection:** Exceeds 2000 V (HBM)  

This device is commonly used in data communication systems, bus interface applications, and general-purpose logic circuits.
