74GTLPH306DGVRE4

Overview

The SN74GTLPH306DGVRE4 is a bidirectional voltage-level translator manufactured by Texas Instruments. It operates within the GTLPH logic family and features an 8-bit wide bus architecture with independent direction control. The device utilizes a 24-pin TVSOP package, providing eight A-side pins and eight B-side pins for data transfer. It supports a VCCA supply range of 1.14 V to 1.26 V and a VCCB supply range of 3.15 V to 3.45 V. The component includes a dedicated VREF pin for GTL termination matching and a DIR pin for controlling signal flow direction.

Feature Summary

• Bidirectional data translation between low-voltage LVTTL domains and GTL-compatible buses
• Independent direction control via a dedicated DIR pin for flexible signal routing
• Integrated VREF pin for precise GTL voltage reference termination matching

Applications

• Interfacing LVTTL microprocessors with GTL memory subsystems
• Data bus translation in high-speed digital communication systems
• System-on-chip interfaces requiring mixed-voltage level compatibility

Procurement Notes

Verify the specific suffix 'E4' against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance details. Ensure the TVSOP-24 package dimensions match your PCB footprint requirements. Confirm that the operating temperature range meets your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when interfacing 1.2 V logic with 3.3 V GTL loads. The GTLPH series offers improved performance over standard GTL devices. Ensure the design accommodates the separate VCCA and VCCB power rails. Verify that the DIR pin logic levels are compatible with the controlling processor outputs.

Part Context

This part belongs to the SN74GTLPH series of advanced voltage translators. It is designed for applications requiring reliable data transfer between different voltage domains. The GTLPH family provides enhanced speed and lower power consumption compared to earlier generations. It serves as a critical interface component in complex digital systems.

Replacement Considerations

Check for SN74GTLPH306DGVR or SN74GTLPH306DGV as potential equivalents. Verify package compatibility and electrical parameter alignment. Confirm that any substitute maintains the same bidirectional functionality and voltage level support.
