Overview
The SN65LVDS31PWG4, produced by Texas Instruments, is a high-speed differential line driver that implements the Low-Voltage Differential Signaling (LVDS) protocol. This quad driver is designed to operate at speeds of up to 400 Mbps, making it suitable for high-speed data transmission applications. The device operates from a single 3.3-V supply and is compatible with Low-Voltage TTL (LVTTL) logic input levels. It is also pin-compatible with several other industry-standard devices, such as the AM26LS31, MC3487, and μA9638.
