SN74GTLP2033DGGR

Specialty Logic Overview

The SN74GTLP2033DGGR is an 8-bit LVTTL-to-GTLP adjustable edge-rate registered bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and supports bidirectional data transfer between LVTTL logic cards and GTLP signal backplanes. The device features high drive capability with 100 mA output current, enabling operation on heavy loads with equivalent impedances as low as 11 Ω. It incorporates TI-OPC circuitry to limit overshoot during low-to-high transitions and OECTM circuits to reduce electromagnetic interference. The component utilizes a 48-pin TSSOP package.

Specialty Logic Feature Summary

• Provides transparent, latched, and flip-flop mode data transmission for flexible system integration.
• Adjustable edge rate control allows optimization of rise and fall times based on backplane load conditions.
• Includes Ioff circuitry to disable outputs when the device is powered down, preventing current backflow.

Specialty Logic Applications

• High-speed interface connections between LVTTL logic cards and GTLP signal backplanes
• Data transmission systems requiring adjustable edge rates for signal integrity optimization
• Heavy-load backplane environments requiring high drive capability

Specialty Logic Procurement Notes

Verify the specific suffix 'DGGR' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with the required operating temperature range and check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when designing interfaces that require conversion between LVTTL and GTLP logic levels with precise control over signal transition speeds. The integrated adjustable edge rate feature makes it suitable for complex backplane designs where minimizing electromagnetic interference and managing signal reflections are critical requirements for maintaining data integrity at high frequencies.

Specialty Logic Part Context

This device belongs to the SN74GTLP series of logic ICs, specifically designed for high-performance voltage level translation. It shares functional similarities with the SN74FB2033 but is optimized for GTLP signaling standards. The product falls under the category of registered bus transceivers, providing robust signal buffering and direction control for digital communication systems.

Specialty Logic Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic equivalents, as GTLP-specific features like OPC and ERC may not be present in standard TTL replacements.
