74LVC16240ADGG,112

Overview

The 74LVC16240ADGG,112 is a 16-bit inverting buffer/line driver with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs and outputs for mixed logic interfacing. The device includes four output enables (1OE, 2OE, 3OE, 4OE) controlling groups of four outputs each. It supports partial power-down applications via IOFF circuitry to prevent backflow current. The component is housed in a TSSOP48 package (SOT362-1) and complies with JEDEC standards for various voltage ranges.

Feature Summary

• Provides 5 V tolerance on both inputs and outputs to facilitate direct interfacing with 5 V logic devices.
• Incorporates dedicated IOFF circuitry to disable outputs and eliminate damaging backflow currents during partial power-down states.
• Features low inductance multiple power and ground pins designed to minimize noise and ground bounce effects.

Applications

• Mixed 3.3 V and 5 V logic system interfacing
• Partial power-down bus buffering applications
• High-speed data line driving

Procurement Notes

Verify the specific ordering suffix matches the required temperature range and packaging configuration. Confirm that the TSSOP48 package variant aligns with the target PCB footprint requirements. Ensure the procurement channel sources directly from authorized distributors to guarantee product authenticity and adherence to the latest manufacturing revisions.

Selection Notes

Select this component when designing systems requiring 16-bit inverting buffering with 5 V tolerance capabilities. It is suitable for applications needing configurable 3-state outputs controlled by separate enable signals. Consider its wide operating voltage range and low power consumption characteristics for portable or battery-operated electronic designs.

Part Context

This device belongs to the 74LVC family of high-speed CMOS logic products. It serves as a buffer and line driver solution within the broader portfolio of Nexperia integrated circuits. The part is functionally similar to other 16-bit buffers but is distinguished by its specific 5 V tolerance and inverting logic characteristics.

Replacement Considerations

Check for compatible parts such as the 74LVC16240ADGG,118 which shares the same functional specifications and package type. Verify pin compatibility and electrical parameters before substituting any alternative components in existing designs.

FAQ

How does the device handle partial power-down conditions?

The device utilizes IOFF circuitry to automatically disable the outputs, preventing damaging backflow current through the component when it is powered down.

What is the function of the nOE pins?

The nOE pins (1OE, 2OE, 3OE, 4OE) act as active LOW output enables. A HIGH level on these pins forces the corresponding outputs into a high-impedance OFF-state.
