SN74GTLPH3245ZKFR

Translators, Level Shifters Overview

The SN74GTLPH3245ZKFR is a high-drive, 32-bit bus transceiver partitioned into four 8-bit segments. It provides LVTTL-to-GTLP and GTLP-to-LVTTL signal-level translation for asynchronous communication between data buses. The device operates with a supply voltage (VCC) of 3.15 V to 3.45 V and supports live insertion via Ioff, power-up 3-state, and BIAS VCC features. It includes adjustable edge-rate control (ERC) to optimize rise and fall times for distributed loads.

Translators, Level Shifters Feature Summary

• Bidirectional interface between GTLP signal levels and LVTTL logic levels
• Adjustable edge-rate control (ERC) input selects GTLP rise and fall times
• Supports live insertion through Ioff, power-up 3-state, and BIAS VCC circuitry
• TI-OPC circuitry limits ringing on unevenly loaded backplanes

Translators, Level Shifters Applications

• High-speed backplane operation
• Asynchronous communication between data buses
• Live-insertion applications

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix 'ZKFR' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating temperature range and voltage levels before procurement.

Translators, Level Shifters Selection Notes

Select this component when interfacing cards operating at LVTTL logic levels with backplanes requiring GTLP signal levels. Consider the adjustable edge-rate control feature for optimizing signal integrity in heavily loaded distributed systems.

Translators, Level Shifters Part Context

This part belongs to the Widebus+ family from Texas Instruments. It is designed for high-speed interfaces where reduced output swing and improved differential inputs are necessary for maintaining signal integrity at higher frequencies.

Translators, Level Shifters Replacement Considerations

Consult official substitution guides for compatible parts within the GTL/GTLP series. Verify pinout and electrical characteristics match before replacing.
