V62/03667-01YE

Overview

V62/03667-01YE is an octal buffer and line driver from the SN74LVTH244A-EP Enhanced Product series by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 3.6 V, supporting mixed-mode signal operation with 5-V tolerant inputs and outputs while utilizing 3.3-V logic levels. The device features two independent 4-bit drivers with separate output-enable (OE) control pins. It incorporates active bus-hold circuitry on data inputs to maintain valid logic states without external resistors. Designed for hot-insertion applications, it provides Ioff and power-up 3-state functionality to prevent current backflow and driver conflicts during power transitions.

Feature Summary

• Supports mixed-mode signal operation allowing 5-V input and output voltages with 3.3-V VCC operation
• Features active bus-hold circuitry on data inputs to eliminate the need for external pullup or pulldown resistors
• Provides Ioff and power-up 3-state support to enable safe hot-insertion and prevent driver conflicts

Applications

• Hot-insertion applications requiring controlled high-impedance states during power transitions
• Mixed-signal systems interfacing 5-V environments with 3.3-V low-voltage logic
• Unregulated battery-powered operations down to 2.7 V

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as this part number corresponds to the TSSOP variant. Confirm that the Enhanced Product qualification pedigree meets your project's reliability standards. Ensure compliance with export regulations if applicable. Cross-reference the datasheet revision date to confirm the technical specifications align with your design requirements before finalizing procurement.

Selection Notes

Select this component when designing systems that require robust buffering between different voltage domains, specifically bridging 5-V and 3.3-V logic. The inclusion of bus-hold circuitry simplifies board layout by removing the need for discrete pull resistors. Consider its extended temperature range and enhanced diminishing manufacturing sources support if long-term availability and environmental resilience are critical factors for the application.

Part Context

This component belongs to the SN74LVTH244A-EP family, which represents Texas Instruments' Enhanced Product line. These parts are designed with controlled baselines, including single assembly and fabrication sites, to ensure consistent quality. The EP designation indicates adherence to stricter qualification standards compared to standard catalog devices, making them suitable for demanding industrial and military-grade applications.

Replacement Considerations
