Overview
The SN75LVDT388ADBTR is an octal low-voltage differential signaling (LVDS) receiver produced by Texas Instruments. This component is part of a family of high-speed differential line receivers designed to meet or exceed the requirements of the ANSI TIA/EIA-644 standard. It operates from a single 3.3-V supply and is packaged in a 38-pin Thin Shrink Small-Outline Package (TSSOP) with a 20-mil terminal pitch. The device is optimized for point-to-point baseband data transmission over controlled impedance media, such as printed-circuit board traces, backplanes, or cables, and is particularly suited for applications requiring high-speed data transfer with low power consumption.
