SN74GTLP22034DGVR

Specialty Logic Overview

The SN74GTLP22034DGVR is an 8-bit LVTTL-to-GTLP registered transceiver in a TVSOP-48 package. It provides bidirectional signal-level translation between cards operating at LVTTL logic levels and backplanes using GTLP signals. The device features split LVTTL ports for feedback, adjustable edge-rate control (ERC), and high-drive outputs. It supports transparent, latched, and flip-flop data modes with live-insertion capabilities.

Specialty Logic Feature Summary

• Bidirectional interface between GTLP signal levels and LVTTL logic levels
• Split LVTTL port provides a feedback path for control and diagnostics monitoring
• Variable edge-rate control input selects GTLP rise and fall times for optimal data-transfer rate and signal integrity
• Supports live insertion via Ioff, power-up 3-state, and BIAS VCC circuitry

Specialty Logic Applications

• High-speed interface between cards operating at LVTTL logic levels and a backplane operating at GTLP signal levels
• Distributed load backplane applications requiring optimized signal integrity
• Live-insertion systems utilizing precharge and isolation features

Specialty Logic Procurement Notes

Verify the specific ordering suffix DGVR to confirm the TVSOP-48 tape and reel packaging configuration. Confirm that the component meets RoHS3 compliance standards as specified in the manufacturer documentation. Ensure design compatibility with the required supply voltage ranges and termination voltages for the target application environment.

Specialty Logic Selection Notes

Select this component when true logic translation between LVTTL and GTLP is required alongside registered data transfer. The split A-port allows simultaneous monitoring of input and output states. Consider the adjustable edge-rate feature if system noise margins require optimization of signal transition speeds on heavily loaded backplanes.

Specialty Logic Part Context

This device belongs to the Texas Instruments Widebus family and utilizes OEC and TI-OPC circuitry to improve signal integrity and limit ringing on unevenly loaded backplanes. It offers functionality similar to the SN74FB2033 but implements true GTLP logic rather than open-collector requirements.
