74LVC16240ADGG,518

Overview

The Nexperia 74LVC16240ADGG,518 is a 16-bit inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and supports inputs driven by either 3.3 V or 5 V devices. The device includes four output enables (1OE, 2OE, 3OE, 4OE), each controlling four outputs. It incorporates IOFF circuitry for partial power-down applications to prevent backflow current. The component is housed in a TSSOP48 plastic thin shrink small outline package (SOT362-1) and is specified for operation from -40 °C to +125 °C.

Feature Summary

• Provides five-volt tolerant inputs and outputs for interfacing with 5 V logic systems.
• Features IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down.
• Utilizes a MULTIBYTE flow-through standard pin-out architecture with low inductance multiple power and ground pins.

Applications

• Mixed 3.3 V and 5 V application environments
• Partial power-down system configurations
• Direct interface with TTL levels

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature rating. Confirm the component status against the latest manufacturer documentation to ensure production availability. Cross-reference the datasheet revision history for any updates to electrical characteristics or package outlines prior to finalizing procurement specifications.

Selection Notes

Select this component when designing circuits requiring 16-bit inverting buffering with three-state control. Ensure the design accommodates the wide supply voltage range and utilizes the dedicated output enable pins for managing high-impedance states. Verify that the thermal dissipation requirements align with the package's total power dissipation limits across the intended operating temperature range.

Part Context

This part belongs to the 74LVC16240A family of 16-bit buffers and line drivers manufactured by Nexperia. It is designed for high-speed digital signal processing applications where level shifting between different voltage domains is necessary. The device complements other bus transceivers and logic ICs within the broader 74LVC series portfolio.

Replacement Considerations

Consult official Nexperia documentation for confirmed substitute part numbers. Verify functional compatibility regarding pinout, voltage tolerance, and propagation delay before substituting.
