- **ESD Protection:** ±8 kV (HBM)  

### **Descriptions:**  
The SN65LVDS9638DGKR is a single-channel LVDS differential line driver designed for high-speed data transmission. It converts single-ended CMOS/TTL signals into low-voltage differential signals, reducing EMI and power consumption while maintaining signal integrity over long distances.  

### **Features:**  
- High-speed signaling up to 400 Mbps  
- Low power consumption  
- 3.3 V supply operation  
- Compatible with TIA/EIA-644 LVDS standard  
- High noise immunity due to differential signaling  
- Short propagation delay for high-speed applications  
- ESD protection for robustness  
- Small VSSOP-8 package for space-constrained designs  

This device is commonly used in applications such as high-speed data transmission, telecommunications, and industrial systems requiring reliable signal integrity.

Alternative Part Number

  • DS90LV047ATMTC --: Quad LVDS driver from TI's DS90LV series, functionally equivalent to the SN65LVDS9638 with similar signaling and supply requirements.
  • FIN1047MTCX --: Quad LVDS driver in TSSOP package offering comparable data rates and pin-compatible functionality as a cross-vendor alternative.
  • MAX9123EUE+ --: Quad LVDS line driver with similar performance characteristics and supply voltage, suitable as a drop-in functional replacement.
  • DS90LV031ATMX --: Quad LVDS line driver from TI's DS90LV series, functionally equivalent to the SN65LVDS9638 with similar signaling and pinout, widely available.
  • FIN1031MX --: Quad LVDS driver offering comparable data rates and low-voltage differential signaling performance, suitable drop-in alternative from a different series.
  • MAX9123ESE --: Quad LVDS line driver with similar electrical characteristics and supply voltage, usable as an alternative when TI parts are unavailable.
