SN74GTLP817PW

Translators, Level Shifters Overview

The SN74GTLP817PW is a medium-drive fanout driver providing LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation. It features a 1-to-6 fanout driver for GTLP-to-LVTTL conversion and a 1-to-2 fanout driver for LVTTL-to-GTLP conversion, both with inverting data polarity. The device operates at VCC = 3.3V (range 3.15V to 3.45V) with VTT = 1.5V and VREF = 1V for GTLP levels. It includes OEC circuitry, variable edge-rate control (ERC), Ioff, and power-up 3-state support. The PW package contains 24 pins.

Translators, Level Shifters Feature Summary

• Bidirectional interface between GTLP signal levels and LVTTL logic levels
• Variable Edge-Rate Control (ERC) input selects GTLP rise and fall times
• Ioff and Power-Up 3-State Support for hot insertion applications
• Distributed VCC and GND pins minimize high-speed switching noise

Translators, Level Shifters Applications

• High-speed backplane operation connecting cards operating at LVTTL logic levels
• Hot-insertion applications requiring output isolation during power-down
• System designs optimizing data-transfer rate and signal integrity in distributed loads

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP package with 24 pins and tube packaging. Confirm the active production status and RoHS compliance details via the latest Texas Instruments documentation before finalizing procurement specifications.

Translators, Level Shifters Selection Notes

Select this component when a bidirectional translator between LVTTL and GTLP standards is required. Ensure the design utilizes the ERC pin to manage edge rates for the specific backplane load impedance. Verify that the 5-V tolerant inputs are compatible with the system's control voltage levels.
