SN74GTLPH32945ZKER

Translators, Level Shifters Overview

The SN74GTLPH32945ZKER is a medium-drive, 32-bit bus transceiver from the Widebus+ family. It provides LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation for high-speed asynchronous communication. The device is partitioned into four 8-bit segments with non-inverting data polarity. It operates at VCC of 3.15 V to 3.45 V and supports live insertion via Ioff, power-up 3-state, and BIAS VCC circuitry. Propagation delay ranges from 2.1 ns to 6.3 ns.

Translators, Level Shifters Feature Summary

• Provides bidirectional interface between GTLP signal levels and LVTTL logic levels
• Features TI-OPC circuitry to limit ringing on unevenly loaded backplanes
• Supports live insertion through Ioff, power-up 3-state, and BIAS VCC capabilities
• Includes active bus-hold circuitry to maintain valid logic states on unused inputs

Translators, Level Shifters Applications

• High-speed interface between cards operating at LVTTL logic levels and backplanes operating at GTLP signal levels
• Asynchronous communication between data buses in distributed load environments
• Live-insertion applications requiring hot-swap capability without disturbing active data

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix ZKER corresponds to the specified tape-and-reel packaging and temperature range as documented in official Texas Instruments datasheets. Confirm compatibility with required VTT and VREF voltage levels for the target GTLP application before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL devices with GTLP backplanes requiring medium-drive strength. Ensure the design accommodates the specific VTT and VREF requirements for optimal noise margins. Consider the package type and thermal characteristics suitable for the intended PCB layout and operating environment.
