SN75LVDS9638D

Drivers, Receivers, Transceivers Overview

The SN75LVDS9638D is a dual-channel differential line driver implementing Low-Voltage Differential Signaling (LVDS) characteristics. It operates from a single 3V to 3.6V supply and accepts LVTTL logic inputs. The device provides two current-mode drivers that deliver a minimum differential output voltage magnitude of 247 mV into a 100-ohm load. It supports signaling rates up to 155 Mbps with typical propagation delays of 6 ns. The component is housed in an 8-pin SOIC package and is characterized for operation within the 0°C to 70°C temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Implements ANSI TIA/EIA-644 LVDS electrical standards for high-speed data transmission
• Features low-voltage TTL input levels compatible with 3.3V logic systems
• Provides high-impedance state when disabled or during power-off conditions

Drivers, Receivers, Transceivers Applications

• Point-to-point baseband data transmission over controlled impedance media
• Data transfer across printed-circuit board traces and backplanes
• IEEE 1394 transceiver interface circuits

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type, lead finish, and moisture sensitivity level. Ensure the selected variant matches the required operating temperature range and RoHS compliance status for the intended production environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring differential signaling with LVTTL compatibility. Verify that the system operates within the specified 3V to 3.6V supply range and that the PCB layout accommodates the 8-pin SOIC footprint. Confirm that the target data rate does not exceed the 155 Mbps specification.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN75LVDS family of high-speed differential line drivers. It shares core electrical specifications with the SN75LVDS31 but differs in channel count and pin configuration. Both devices are designed to reduce power consumption while increasing switching speeds compared to traditional 5V differential standards.

Drivers, Receivers, Transceivers Replacement Considerations

The SN75LVDS9638DGK serves as a direct pin-compatible alternative in a VSSOP package. Designers must verify thermal dissipation requirements and physical footprint constraints when substituting between the SOIC and VSSOP variants.
