SN75DP139RSBR

Specialized Overview

The SN75DP139RSBR is a DisplayPort to TMDS translator manufactured by Texas Instruments. It converts DisplayPort signals to TMDS for HDMI compatibility. The device operates within a supply voltage range of 3 V to 3.6 V and draws a typical operating current of 110 mA. It supports a maximum working frequency of 250 MHz. The component is housed in a WQFN-40 package suitable for surface mount technology. It functions reliably across an ambient temperature range from 0 °C to +85 °C.

Specialized Feature Summary

• Translates DisplayPort input signals into TMDS output format
• Supports high-speed data transmission up to 250 MHz
• Designed for low power consumption applications

Specialized Applications

• Desktop computer display interfaces
• Laptop video output modules
• All-in-one PC display systems

Specialized Procurement Notes

Verify the specific suffix RSBR against the official datasheet to confirm the WQFN-40 package variant. Ensure the ordering information matches the required tape and reel packaging configuration. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Specialized Selection Notes

Select this component when a compact WQFN-40 footprint is required for DisplayPort to HDMI conversion. Compare pin counts with the RGZ series if a 48-pin VQFN package offers better thermal or routing advantages for the specific PCB layout constraints.

Specialized Part Context

This part belongs to the SN75DP139 family of display interface integrated circuits. It serves as a bridge between modern DisplayPort sources and legacy TMDS-based displays. The RSBR suffix specifically denotes the WQFN-40 package option, distinguishing it from other variants in the same functional family.

Specialized Replacement Considerations

The SN75DP139RGZR and SN75DP139RGZT are confirmed substitutes within the same product family. These alternatives utilize a 48-pin VQFN package instead of the 40-pin WQFN. Verify pinout compatibility and physical dimensions before implementing any cross-package replacement.
