SN74GTLP1394D

Translators, Level Shifters Overview

The SN74GTLP1394D is a high-drive, 2-bit, 3-wire bus transceiver designed for LVTTL to GTLP and GTLP to LVTTL signal-level translation. It supports transparent and inverted data transmission with independent LVTTL input and output pins for feedback paths. The device operates within a supply voltage range of 3.15 V to 3.45 V, featuring a propagation delay of 8.6 ns and a maximum operating temperature of +85°C. It utilizes a 16-pin SOIC package.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between LVTTL logic levels and GTLP backplane signals.
• Includes TI-OPC circuitry to limit ringing and overshoot on unevenly loaded backplanes.
• Features adjustable edge-rate control (ERC) to optimize signal integrity and system data rates.
• Integrates Ioff, power-up three-state, and BiasVCC circuits for safe hot insertion.

Translators, Level Shifters Applications

• High-speed interface between cards operating at LVTTL levels and backplanes using GTLP signals
• Integration with Texas Instruments 1394 backplane physical layer controllers
• Hot insertion applications requiring precharging and biasing of backplane connections

Translators, Level Shifters Procurement Notes

Verify the specific suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments, as availability may vary by region and production cycle.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL logic with GTLP backplanes requiring high drive capability and adjustable edge rates. Ensure the design accommodates the 3.15 V to 3.45 V supply voltage range and utilizes the ERC pin for signal integrity optimization in heavy load scenarios.

Translators, Level Shifters Part Context

Part of the SN74GTLP family targeting telecommunication and data communication backplanes. It serves as a specialized translator for Gigabit Transceiver Logic Plus standards, enabling faster operation than standard LVTTL by reducing output swing and improving noise margins through differential inputs.

Translators, Level Shifters Replacement Considerations

Check for SN74GTLP1394PW or SN74GTLP1394DGVR equivalents. Verify pin compatibility and electrical specifications before substitution.
