74LVC16240ADL,118

Overview

The Nexperia 74LVC16240ADL,118 is a 16-bit inverting buffer and line driver featuring 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V and provides 5 V tolerant inputs and outputs for mixed logic interfacing. The device includes IOFF circuitry to prevent backflow current during partial power-down. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerance on both inputs and outputs to facilitate direct interfacing with 5 V logic systems.
• Incorporates IOFF circuitry that disables outputs to prevent damaging backflow currents when the device is powered down.
• Features low inductance multiple power and ground pins designed to minimize noise and ground bounce effects.

Applications

• Mixed 3.3 V and 5 V system applications
• Partial power-down environments requiring bus isolation
• High-speed data transmission lines

Procurement Notes

Verify the specific package designation associated with the 'DL' suffix against official Nexperia documentation before procurement. Confirm that the required operating temperature range aligns with the specified -40 °C to +125 °C limits. Ensure input voltage levels do not exceed the absolute maximum ratings defined in the datasheet to prevent permanent damage.

Selection Notes

Select this component for designs requiring 16-bit buffering with inverted logic and 3-state control. It is suitable for applications needing direct interface with TTL levels or 5 V devices while operating from lower supply voltages. Verify that the TSSOP48 package dimensions fit the available PCB footprint constraints.

Part Context

This part belongs to the 74LVC16240A family of 16-bit buffers. The 'DL' suffix indicates a specific package variant, which was noted as removed in revision history v.5 but remains valid under SOT370-1 specifications. It shares functional characteristics with other LVC series drivers but offers distinct pinout configurations.

Replacement Considerations

Check for 74LVC16240ADGG variants if TSSOP48 (SOT362-1) packaging is acceptable instead of the DL package. Ensure any substitute maintains the same 16-bit width, inverting polarity, and 3-state output capabilities.
