74LVC16240ADGG-Q1J

Overview

The Nexperia 74LVC16240ADGG-Q1J is a 16-bit inverting buffer and line driver with three-state outputs, housed in a TSSOP-48 package. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs driven by 3.3 V or 5 V devices. The device features four output enables (1OE, 2OE, 3OE, 4OE) controlling four outputs each. High-level output current is -24 mA and low-level output current is 24 mA. Static current is 100 nA maximum, with operating power consumption at 80 uA. It functions from -40 °C to +125 °C and meets AEC-Q100 Grade 1 qualification.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 Grade 1 standards for automotive applications.
• Provides five-volt tolerant inputs and outputs, enabling direct interfacing with mixed 3.3 V and 5 V logic environments.
• Includes IOFF circuitry that disables outputs during partial power-down to prevent damaging backflow currents.

Applications

• Mixed 3.3 V and 5 V logic level translation interfaces
• Automotive electronic systems requiring AEC-Q100 compliance
• Partial power-down mode applications utilizing IOFF functionality

Procurement Notes

Verify the specific suffix 'Q1J' against the manufacturer's official ordering information to confirm it aligns with the AEC-Q100 Grade 1 qualified version described in the datasheet. Ensure the package designation matches SOT362-1 (TSSOP48). Confirm temperature range specifications match the required operational environment limits before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring 16-bit inverting buffering with three-state control in automotive environments. It is suitable for applications needing direct interface with TTL levels and wide supply voltage flexibility between 1.2 V and 3.6 V. Consider its low power consumption and ESD protection capabilities for robust system design.

Part Context

This part belongs to the 74LVC16240A-Q100 family of 16-bit buffers. It shares functional similarities with other LVC series drivers but is distinguished by its automotive qualification and specific pinout configuration in the TSSOP48 package. It serves as a specialized variant designed for high-reliability automotive electronics compared to standard commercial logic families.

Replacement Considerations

The non-automotive grade 74LVC16240ADGG may serve as a functional substitute if automotive qualification is not required. Verify pin compatibility and electrical characteristics carefully before substitution.

FAQ

How does the IOFF feature function?

The IOFF circuitry disables the outputs when the device is powered down, preventing potentially damaging backflow current through the device.

What is the input voltage tolerance?

Inputs can be driven from either 3.3 V or 5 V devices, allowing use in mixed voltage environments.
