SN74GTLPH32945KR

Translators, Level Shifters Overview

The SN74GTLPH32945KR 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. Partitioned into four 8-bit segments, it interfaces cards operating at LVTTL logic levels with backplanes using GTLP signals. The device supports live insertion via Ioff, power-up 3-state, and BIAS VCC circuitry. It operates within a supply voltage range of 3.15 V to 3.45 V and an ambient temperature range of -40°C to 85°C.

Translators, Level Shifters Feature Summary

• Supports live insertion through Ioff, power-up 3-state, and BIAS VCC features
• TI-OPC circuitry limits ringing on unevenly loaded backplanes
• Active bus-hold circuitry maintains valid logic states on unused inputs

Translators, Level Shifters Applications

• High-speed backplane communication systems
• Asynchronous data bus interfaces
• Live-insertion card applications
• LVTTL to GTLP signal level translation

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix KR corresponds to the LFBGA package and tape-and-reel configuration. Confirm that the component meets the required environmental specifications for your application. Ensure compatibility with the intended supply voltage and termination requirements before finalizing procurement decisions.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL logic devices with GTLP backplanes requiring medium drive strength. Consider its partitioned architecture for managing multiple independent data buses. Evaluate the necessity of live-insertion capabilities and TI-OPC benefits for your specific system design constraints.
