SN65LVDS9638DG4

Drivers, Receivers, Transceivers Overview

The SN65LVDS9638DG4 is a dual LVDS transmitter manufactured by Texas Instruments, designed for high-speed data transmission. It converts LVTTL inputs to differential LVDS outputs, supporting data rates up to 400 Mbps. The device operates on a single 3V to 3.6V power supply with a typical current consumption of 13 mA. It features ESD protection exceeding 8 kV and functions within a temperature range of -40°C to +85°C. Packaged in an 8-pin SOIC surface-mount case measuring 4.9mm by 1.58mm, it offers a propagation delay of 1.7 ns and complies with ANSI TIA/EIA-644 standards.

Drivers, Receivers, Transceivers Feature Summary

• Converts low-voltage TTL logic signals into differential LVDS outputs for reliable high-speed communication
• Provides enhanced electrostatic discharge protection to ensure system reliability in noisy environments
• Supports cold standby functionality to maintain signal integrity during redundant system operations

Drivers, Receivers, Transceivers Applications

• High-speed serial data links requiring low voltage differential signaling
• Portable wireless communication devices where battery life extension is critical
• Industrial control systems operating in harsh environmental conditions

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant when ordering, as the DG4 suffix indicates a lead-free version of the standard SN65LVDS9638D. Confirm that the required data rate does not exceed the specified 400 Mbps limit for optimal performance. Ensure the design accommodates the 3V to 3.6V supply voltage range and the -40°C to +85°C operating temperature window. Check for availability constraints if large quantities are needed, as production cycles may vary.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel LVDS driver is needed to interface LVTTL logic with LVDS receivers. It serves as a direct replacement for older AM26LS31 or MC3487 drivers while offering lower power consumption. Consider the 8-pin SOIC package for space-constrained PCB layouts. Verify that the application requires the specific 1.7 ns propagation delay and 350 mV output swing characteristics defined in the datasheet.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SNx5LVDSxx series of low-voltage differential line drivers from Texas Instruments. The series is engineered to meet or exceed ANSI TIA/EIA-644 standards for LVDS interfaces. It shares functional similarities with other members like the SN65LVDS31 but is specifically optimized for dual-driver applications with LVTTL compatibility.

Drivers, Receivers, Transceivers Replacement Considerations

The SN65LVDS9638DGK is a compatible alternative with identical electrical specifications but packaged in VSSOP-8 instead of SOIC. For pin-compatible replacements, verify that the substitute supports the same 400 Mbps data rate and LVTTL input levels.
