Overview
The SN74LVT16244B, specifically the 74LVT16244BDGGRG4, is a 16-bit buffer and line driver produced by Texas Instruments. This device is designed for low-voltage (3.3-V) VCC operation and can interface with 5-V system environments, making it versatile for various applications. It can be configured as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. The device features true outputs and symmetrical active-low output-enable (OE) inputs, which are essential for managing data flow efficiently.
