155 Mbps dual LVDS driver — what the rating means for the serial link
The TI SN75LVDS9638DGK is a dual-channel LVDS driver rated for 155 Mbps per channel. The 2/0 driver/receiver count means this is a transmit-only device — you pair it with a separate LVDS receiver (like the SN75LVDS9637) for a full duplex link.
Package and footprint — 8-VSSOP
Housed in an 8-VSSOP (DGK suffix), the body is 3.00 mm × 3.00 mm with a 0.65 mm pin pitch. That footprint matches the standard 8-TSSOP/MSOP land pattern, so layout reuse across the TI LVDS family is straightforward. The tube shipping medium is fine for prototype or low-volume builds; for production reels order the tape-and-reel variant (SN75LVDS9638DGKR).
TI lists the SN75LVDS9638DGK as Active.
