SN74GTLPH3245GKFR

Translators, Level Shifters Overview

The SN74GTLPH3245GKFR 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) for optimizing data-transfer rates and signal integrity in 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 interface between cards operating at LVTTL logic levels and backplanes operating at GTLP signal levels
• Asynchronous communication between data buses
• Live-insertion applications requiring precharge and preconditioning of B-port connections

Translators, Level Shifters Procurement Notes

Verify the GKF package designation corresponds to the FBGA-114 plastic package. Confirm the 'R' suffix indicates tape and reel packaging as specified in the ordering information. Ensure the component meets the -40°C to 85°C operating temperature range requirements for your specific application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL logic with GTLP backplane signals requiring high drive capability. Consider the adjustable edge-rate control if system signal integrity optimization is necessary. Verify that the 100 mA high-drive GTLP outputs meet the load impedance requirements of the target backplane architecture.

Translators, Level Shifters Part Context

This part belongs to the Widebus+ family from Texas Instruments. It is designed for high-speed backplane applications where reduced output swing and improved differential inputs enhance performance. The device utilizes OEC circuitry to minimize bus-settling time and electromagnetic interference.
