Description and Introduction

Low Voltage Octal Transceiver/Register with 3-STATE Outputs The 74LVTH646 is a high-performance, low-voltage CMOS device manufactured by Fairchild Semiconductor. It is a 16-bit bus transceiver with 3-state outputs, designed for low-voltage (3.3V) VCC operation but with 5V tolerant inputs and outputs. Key specifications include:

- **Logic Family**: LVTH (Low Voltage TTL with 5V Tolerant Inputs and Outputs)
- **Number of Bits**: 16
- **Supply Voltage (VCC)**: 3.0V to 3.6V
- **Input Voltage (VI)**: 0V to 5.5V
- **Output Voltage (VO)**: 0V to 5.5V
- **Operating Temperature Range**: -40°C to +85°C
- **Output Drive Capability**: ±12mA at 3.3V
- **Propagation Delay**: Typically 3.5ns at 3.3V
- **Package Options**: 48-pin TSSOP, 48-pin SSOP, and 48-pin TVSOP
- **Features**: 
  - 5V tolerant inputs and outputs
  - 3-state outputs for bus-oriented applications
  - Power-off high-impedance inputs and outputs
  - Live insertion/extraction permitted
  - Latch-up performance exceeds 500mA per JESD 78

This device is commonly used in applications requiring bidirectional data flow, such as in data buses, memory interfacing, and communication systems.
