SN65LVDS391PW

The SN65LVDS391PW is a quad LVDS driver manufactured by Texas Instruments, designed to meet or exceed the requirements of the ANSI EIA/TIA-644 standard. This component implements low-voltage differential signaling (LVDS) to reduce power consumption and increase switching speeds, allowing operation with a 3.3V supply rail.

Key electrical characteristics include a signaling rate of up to 630 Mbps, with very low radiation (EMI). It features typical output voltage of 350 mV with a 100-ohm load, propagation delay times less than 2.9 ns, output skew less than 150 ps, and part-to-part skew less than 1.5 ns. The driver offers low power dissipation of 35 mW per driver operating at 200 MHz and enters a high-impedance state when disabled or with VCC below 1.5 V.

Designed for surface mount applications, the SN65LVDS391PW is supplied in a 16-TSSOP package. The LVTTL logic inputs are 5-V tolerant, providing flexibility in system design. Bus-pin ESD protection exceeds 15 kV, enhancing robustness.

This driver is suitable for applications requiring high-speed differential signaling, such as data communication systems, display interfaces, and industrial control systems where signal integrity and low power are critical.
