Description and Introduction

Octal Bus Transceivers With 3-State Outputs The SN74LV245ANSR is a 3.3-V octal bus transceiver manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Logic Type:** Octal Bus Transceiver  
- **Voltage Supply:** 3V to 3.6V (3.3V nominal)  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package / Case:** 20-SOIC (0.209", 5.30mm Width)  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 6.5 ns (max) at 3.3V  
- **High-Level Output Current:** -12mA  
- **Low-Level Output Current:** 12mA  
- **Input Capacitance:** 3.5 pF (typical)  
- **Output Capacitance:** 8 pF (typical)  

### **Descriptions:**  
- The SN74LV245ANSR is an octal bus transceiver designed for asynchronous communication between data buses.  
- It features non-inverting 3-state outputs and bidirectional data flow controlled by the direction (DIR) input.  
- The output-enable (OE) input disables the outputs for bus isolation.  
- It operates with a 3.3V supply, making it suitable for low-voltage applications.  

### **Features:**  
- **Wide Operating Voltage Range:** 3V to 3.6V  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **3-State Outputs:** Allows bus isolation when disabled  
- **Low Power Consumption:** ICC typically 10µA  
- **High Drive Capability:** ±12mA output drive at 3.3V  
- **ESD Protection:** Exceeds 2000V per JESD 22  
- **Balanced Propagation Delays:** Ensures reliable signal timing  
- **Latch-Up Performance:** Exceeds 250mA per JESD 17  

This information is sourced from the official Texas Instruments datasheet for the SN74LV245ANSR.
