SN74GTLPH16927VR

Translators, Level Shifters Overview

The SN74GTLPH16927VR is an 18-bit LVTTL-to-GTLP bus transceiver from the Widebus family, designed for high-speed interface applications. It operates within a supply voltage range of 3.15 V to 3.45 V and supports data transfer rates up to 175 MHz. The device provides bidirectional signal translation between GTLP backplane levels and LVTTL logic levels. Key electrical characteristics include medium-drive GTLP outputs with a current capability of 50 mA and LVTTL outputs rated at ±24 mA. Propagation delays typically reach 6.5 ns in the A-to-B direction. It features source-synchronous clock outputs (SSCLK) and includes live-insertion support via Ioff, power-up 3-state, and BIASVCC circuitry.

Translators, Level Shifters Feature Summary

• TI-OPC circuitry actively limits overshoot on unevenly loaded backplanes to improve signal integrity.
• OEC circuitry reduces electromagnetic interference and improves signal integrity.
• Flexible setup-time adjustment (FSTA) feature minimizes skew between clock and data outputs.
• Supports live insertion through Ioff, power-up 3-state, and BIASVCC precharge capabilities.

Translators, Level Shifters Applications

• High-speed backplane interfaces requiring LVTTL-to-GTLP level translation
• Source-synchronous data transfer systems
• Clock-synchronous applications utilizing buffered SYSCLK signals

Translators, Level Shifters Procurement Notes

Verify that the ordering suffix VR corresponds to the TVSOP DGV package type as specified in the datasheet.
