SN74GTLP1394DR

Translators, Level Shifters Overview

The SN74GTLP1394DR is a high-drive, 2-bit bus transceiver designed for LVTTL to GTLP and GTLP to LVTTL signal-level translation. It features adjustable edge-rate control (ERC) and TI-OPC circuits to limit overshoot and improve signal integrity on heavy-load backplanes. The device supports transparent and inverted data transmission with independent LVTTL ports for feedback paths. It operates within a supply voltage range of 3.15 V to 3.45 V and includes Ioff, power-up three-state, and BIASVCC circuits for hot-insertion applications.

Translators, Level Shifters Feature Summary

• Provides bidirectional translation between LVTTL logic levels and GTLP signaling standards for high-speed backplane interfaces.
• Features adjustable edge-rate control (ERC) to optimize system data rates and minimize signal reflections on the bus.
• Incorporates TI-OPC circuitry to effectively limit overshoot and ringing caused by uneven loading or signal transitions.
• Supports hot-insertion operations through integrated Ioff, power-up three-state, and BIASVCC protection mechanisms.

Translators, Level Shifters Applications

• High-speed interface connections between cards operating at LVTTL levels and backplanes using GTLP signals.
• System designs requiring compatibility with Texas Instruments 1394 backplane physical layer controllers.
• Applications necessitating real-time insertion and removal without disrupting valid data on the bus.

Translators, Level Shifters Procurement Notes

Verify the specific package suffix 'DR' corresponds to the SOIC-16 tape-and-reel configuration in official datasheets. Confirm that the GTLP variant matches the required VTT and VREF specifications for your target backplane impedance. Ensure the ERC pin is properly terminated to achieve the desired rise and fall times for your signal integrity requirements.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL peripherals with GTLP-based high-speed backplanes. It is suitable for systems requiring adjustable signal slew rates to manage noise and crosstalk. Consider alternative packages like PW or DGVR if different footprint constraints apply, noting that functional characteristics remain consistent across the SN74GTLP1394 family.

Translators, Level Shifters Part Context

This part belongs to the SN74GTLP1394 series of bus transceivers. It is specifically engineered for high-performance computing environments where signal integrity and hot-swap capabilities are critical. The device complements other GTLP components by providing robust level shifting and drive strength for demanding backplane architectures.

Translators, Level Shifters Replacement Considerations

The SN74GTLP1394PWR and SN74GTLP1394DGVR are functionally equivalent alternatives offering different packaging options such as TSSOP-16 and TVSOP-16 respectively. Verify that the replacement package meets the mechanical constraints of the PCB layout while maintaining identical electrical performance and pinout compatibility.
