SN74GTLPH16912GR

Overview

The SN74GTLPH16912GR is an 18-bit LVTTL-to-GTLP universal bus transceiver manufactured by Texas Instruments. It operates within a supply voltage range of 3.15 V to 3.45 V and features a propagation delay of 6.5 ns. The device utilizes a TSSOP-56 package and supports surface-mount installation. It functions as a bidirectional translator between Low Voltage Transistor-Transistor Logic (LVTTL) and GTL Plus (GTLP) signaling standards, with a maximum operating current of 50 mA.

Feature Summary

• Provides bidirectional translation between LVTTL and GTLP logic families
• Integrates 18 channels for high-density data transfer applications
• Features three-state outputs for efficient bus management

Applications

• High-speed digital signal processing systems
• Data communication interfaces requiring mixed-voltage level compatibility
• Computer peripheral interconnects utilizing GTL+ signaling

Procurement Notes

Verify the specific suffix GR indicates the TSSOP-56 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design accommodates the specified 3.15 V to 3.45 V power supply requirements for proper operation within the -40°C to +85°C temperature range.

Selection Notes

Select this component when interfacing LVTTL sources with GTLP loads in 18-bit wide configurations. The TSSOP-56 package offers a compact footprint suitable for space-constrained designs. Consider the 6.5 ns propagation delay for timing analysis in high-frequency applications requiring precise synchronization between different logic voltage domains.

Part Context

This part belongs to the SN74GTLPH16912 series, designed specifically for translating between LVTTL and GTLP standards. It serves as a bridge in systems where different logic families must communicate directly. The device simplifies board design by eliminating external level-shifting components for these specific protocols.

Replacement Considerations

Check for variants such as SN74GTLPH16912DGG or SN74GTLPH16912DL if alternative packages like TVSOP or SSOP are required. Verify pinout compatibility before substituting with other members of the GTLPH family.
