SN74GTLP1394PWR

Translators, Level Shifters Overview

The SN74GTLP1394PWR is a high-drive, 2-bit, 3-wire bus transceiver designed for LVTTL to GTLP and GTLP to LVTTL signal-level translation. It operates within a supply voltage range of 3.15 V to 3.45 V and features a propagation delay of 8.6 ns. The device supports transparent and inverted data transmission modes with independent LVTTL input and output pins for feedback paths. It utilizes a TSSOP-16 package and functions across an operating temperature range from -40°C to +85°C.

Translators, Level Shifters Feature Summary

• Provides bidirectional signal translation between LVTTL logic levels on card interfaces and GTLP signal levels on backplanes.
• Includes TI-OPC circuitry to limit ringing and overshoot caused by uneven loading or signal transitions, improving signal integrity.
• Features adjustable edge rate control (ERC) to optimize system data transmission rates and manage signal integrity under varying load conditions.
• Integrates Ioff, power-up three-state, and BIAS VCC circuits to prevent current backflow and bus interference during hot insertion.

Translators, Level Shifters Applications

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

Translators, Level Shifters Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-16 surface-mount package configuration. Confirm that the required supply voltage aligns with the specified 3.15 V to 3.45 V operational window. Ensure environmental specifications meet the -40°C to +85°C industrial temperature range requirements for your target application environment.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL-based peripherals with GTLP-compliant backplane architectures. It is suitable for designs requiring adjustable edge rates to mitigate signal integrity issues in heavy-load scenarios. Consider its integrated protection features for hot-swap applications where bus stability during insertion is critical.

Translators, Level Shifters Part Context

This device belongs to the SN74GTLP family of Gunning-transceiver-logic-plus components from Texas Instruments. These devices are engineered specifically for telecommunications and data communications backplanes. The GTLP standard serves as a derivative of the JEDEC JESD 8-3 GTL specification, offering improved noise margins and drive capabilities compared to standard GTL.
