What this LVDS receiver does on the board
The Texas Instruments SN75LVDS388ADBTR is an eight-channel LVDS receiver in a 38-pin TSSOP package. It accepts differential LVDS signals and converts them to single-ended CMOS logic levels, handling data rates up to 200 Mbps per channel. The 0/8 driver/receiver count means this device is a pure receiver bank—no drivers on-chip—so it fits designs where the transmit side is handled elsewhere, such as a companion LVDS driver or serializer.
That means TI no longer manufactures it and there is no official last-time-buy window open. Availability and pricing fluctuate and must be confirmed at quote time. There is no official TI-recommended replacement listed in the lifecycle record, so a drop-in substitute requires careful evaluation of pinout, electrical specs, and timing.
Package and supply — what to check at layout
The SN75LVDS388ADBTR comes in a 38-lead TSSOP (TFSOP variant) with a 4.40 mm body width and 0.5 mm pitch. It is a surface-mount device, so the board footprint must match the TSSOP-38 land pattern. Decoupling at the package pins should follow standard LVDS practice: a 0.1 µF ceramic close to each supply pin pair, plus a bulk capacitor on the board.
