TB5D1MDE4

Drivers, Receivers, Transceivers Overview

The TB5D1MDE4 is a quad differential PECL driver manufactured by Texas Instruments, housed in a 16-pin SOIC package. It operates with supply voltages ranging from 3.0 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features TTL inputs and pseudo-ECL differential outputs, providing a third-state capability with output voltage below 0.1 V. Electrical characteristics include a maximum propagation delay of 2 ns at 5 V nominal supply and 3.5 ns at 3.3 V nominal supply. It includes built-in lightning protection capable of absorbing large transitions on transmission lines without destroying the device.

Drivers, Receivers, Transceivers Feature Summary

• Built-in lightning protection circuit absorbs large transitions on transmission lines
• Third-state output capability with low impedance level below 0.1 V
• TTL input logic compatible with pseudo-ECL differential outputs
• Pin-equivalent replacement for Agere Systems BDG1A and BPNGA drivers

Drivers, Receivers, Transceivers Applications

• Digital data transmission over balanced transmission lines
• Clock distribution systems requiring differential signaling
• Replacement for legacy Agere Systems BDG1A and BPNGA drivers

Drivers, Receivers, Transceivers Procurement Notes

Verify the RoHS compliance status and lead finish (NIPDAU) against current datasheet revisions before procurement. Confirm the moisture sensitivity level (MSL Level-2) and storage conditions to prevent damage during handling. Ensure the ordering suffix matches the required package type (SOIC D vs DW) as they are distinct physical footprints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a pin-compatible replacement for Agere BDG1A or BPNGA is required. Choose the TB5D1MDE4 specifically for its integrated lightning surge protection, which loads the line during power-down. Verify that the system requires TTL inputs driving PECL outputs rather than standard LVDS signaling.

Drivers, Receivers, Transceivers Part Context

The TB5D1MDE4 belongs to the TB5D1M family of quad differential drivers. It is functionally identical to the TB5D1MD but includes specific environmental and packaging suffixes indicating RoHS compliance and nickel/palladium/gold lead finish. It serves as a direct drop-in replacement for older Agere Systems components in existing designs.

Drivers, Receivers, Transceivers Replacement Considerations

TB5D1MD is the non-RoHS equivalent part number within the same family.
