Description and Introduction

OCTAL BUS TRANSCEIVER (3-STATE NON INVERTING) The **M74HC245RM13TR** is a high-speed CMOS octal bus transceiver manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Logic Family:** HC (High-Speed CMOS)  
- **Number of Bits:** 8 (Octal)  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +125°C  
- **High Noise Immunity:** CMOS technology  
- **Low Power Consumption:** Typical ICC = 4µA (max)  
- **Output Drive Capability:** 10 LSTTL loads  
- **Direction Control:** DIR pin for bidirectional data flow  
- **Output Enable (OE):** Active LOW, tri-state outputs  
- **Package:** SO-20 (Small Outline, 20 pins)  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
The **M74HC245RM13TR** is a bidirectional octal transceiver designed for asynchronous communication between data buses. It allows data transmission from A to B or B to A, depending on the direction control (DIR) pin. The Output Enable (OE) pin disables the outputs when HIGH, placing them in a high-impedance state.  

### **Features:**  
- **Bidirectional Data Flow:** Controlled by DIR pin  
- **Tri-State Outputs:** High impedance when disabled  
- **Wide Operating Voltage:** 2V to 6V  
- **High-Speed Operation:** tPD = 13 ns (typical at 5V)  
- **Balanced Propagation Delays:** Symmetrical output transition times  
- **Low Quiescent Current:** Suitable for battery-operated devices  
- **ESD Protection:** HBM > 2000V, MM > 200V  

This device is commonly used in data bus buffering, memory interfacing, and bidirectional communication systems.
