SN74GTLPH16927GR

Translators, Level Shifters Overview

The SN74GTLPH16927GR is an 18-bit LVTTL-to-GTLP bus transceiver featuring source-synchronous clock outputs. It operates at a supply voltage of 3.3 V with a recommended operating temperature range from -40°C to 85°C. The device supports bidirectional data transfer between LVTTL logic levels and GTLP signal levels, utilizing medium-drive GTLP outputs capable of 50 mA current. It includes features for live insertion, such as Ioff, power-up 3-state, and BIAS VCC support. The component is available in a 56-pin TSSOP (DGG) package.

Translators, Level Shifters Feature Summary

• Provides bidirectional interface between GTLP signal levels and LVTTL logic levels
• Includes buffered SYSCLK signal output for source-synchronous applications
• Features TI-OPC circuitry to limit ringing on unevenly loaded backplanes
• Supports live insertion through Ioff, power-up 3-state, and BIAS VCC circuits

Translators, Level Shifters Applications

• High-speed interface between cards operating at LVTTL logic levels and backplanes operating at GTLP signal levels
• Source-synchronous applications requiring minimized skew between clock and data outputs
• Clock-mode select applications for switching between system-synchronous and clock-synchronous modes

Translators, Level Shifters Procurement Notes

Verify the specific ordering suffix matches the required package type, as the GR suffix denotes a TSSOP package. Confirm that the device status is listed as active for new designs. Ensure compatibility with the specified 3.3 V supply voltage and temperature range. Check for any alternative package options if space constraints differ. Validate that the tape and reel specifications meet manufacturing requirements.

Translators, Level Shifters Selection Notes

Select this component when interfacing LVTTL systems with GTLP backplanes requiring high-speed data transfer. Consider the source-synchronous capabilities if minimizing clock-to-data skew is critical. Evaluate the need for live insertion support features like BIAS VCC. Ensure the design accommodates the medium-drive output strength and distributed load characteristics typical of backplane environments.
