SN75LVDS84ADGGR

Drivers, Receivers, Transceivers Overview

The SN75LVDS84ADGGR is a FlatLink transmitter manufactured by Texas Instruments, designed for high-speed data transmission. It integrates three 7-bit parallel-load serial-out shift registers and four LVDS line drivers within a single integrated circuit. The device converts 21 bits of single-ended LVTTL data into three balanced-pair differential signals plus a clock. It operates from a single 3.3-V supply with typical power consumption of 89 mW. The component supports an input clock frequency range of 31 MHz to 75 MHz and features spread-spectrum clocking (SSC) capability with 3% center spread at a 50-kHz modulation frequency. It is housed in a 48-pin Thin Shrink Small-Outline Package (TSSOP).

Drivers, Receivers, Transceivers Feature Summary

• Integrates internal phase-locked loop (PLL) requiring no external components.
• Converts 21-bit parallel LVTTL inputs to three serial LVDS streams.
• Supports spread-spectrum clocking for reduced electromagnetic interference.
• Includes active-low shutdown/clear control for low-power operation.

Drivers, Receivers, Transceivers Applications

• SVGA, XGA, or SXGA data transmission from controller to display.
• High-speed video and data communication systems.
• Flat panel display interfaces requiring low EMI.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGR' confirms the tape-and-reel packaging format rather than tube packaging. Confirm that the 'A' designation aligns with the commercial temperature range specifications required for the target application environment before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-chip solution is needed to serialize 21-bit parallel data for LVDS transmission. Ensure the system design accommodates the 3.3-V supply voltage and the 48-pin TSSOP footprint. Verify compatibility with downstream receivers such as the SN75LVDS82 or SN75LVDS86/86A for complete link functionality.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75LVDS84 family of FlatLink transmitters. It serves as an improved replacement for the SN75LVDS84 and certain National Semiconductor devices. The 'DGGR' suffix specifically denotes the surface-mount package type combined with tape-and-reel shipping configuration for automated assembly processes.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include SN75LVDS84ADGG and SN75LVDS84ADGGRG4. These variants share identical electrical characteristics and pinouts but differ in packaging format or lead finish compliance.
