Description and Introduction

Octal Bidirectional Transceivers with 3-state Outputs The part HD74LVC245AT is manufactured by Hitachi. It is a 3.3V CMOS octal bus transceiver with 3-state outputs. Key specifications include:

- **Supply Voltage (VCC):** 2.7V to 3.6V  
- **High-Speed Operation:** tpd = 4.3 ns (max) at VCC = 3.3V  
- **Output Current:** ±24 mA at VCC = 3.0V  
- **Power-Down Protection on Inputs and Outputs**  
- **Bus Hold on Data Inputs Eliminates Need for External Pull-up/Pull-down Resistors**  
- **Package:** TSSOP-20  
- **Operating Temperature Range:** -40°C to +85°C  

The device is designed for bidirectional data transmission between buses and supports 3-state outputs for bus-oriented applications.

Description and Introduction

Octal Bidirectional Transceivers with 3-state Outputs The HD74LVC245AT is a high-speed CMOS octal bus transceiver manufactured by Hitachi (now part of Renesas Electronics). Here are its key specifications:  

- **Logic Family**: LVC (Low-Voltage CMOS)  
- **Number of Channels**: 8 (Octal)  
- **Function**: Bidirectional bus transceiver with 3-state outputs  
- **Supply Voltage Range**: 1.65V to 3.6V  
- **High-Speed Operation**: Propagation delay time of 4.2 ns (max) at 3.3V  
- **Input/Output Compatibility**:  
  - 5V tolerant inputs (when VCC ≥ 2.7V)  
  - Supports mixed-voltage operation  
- **Output Drive Capability**: ±24 mA at 3.0V  
- **Power Dissipation**: Low power consumption (ICC = 10 µA max at 3.6V)  
- **Operating Temperature Range**: -40°C to +85°C  
- **Package**: TSSOP-20  
- **Direction Control**: DIR pin controls data flow (A to B or B to A)  
- **Output Enable**: OE pin (active low) for 3-state outputs  

This device is designed for voltage-level translation and bidirectional data transfer in low-voltage systems.
