74ABT16240ADL,118

Buffers, Drivers, Receivers, Transceivers Overview

The 74ABT16240ADL,118 is a 16-bit inverting buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V. The device provides an output capability of +64 mA for low-level states and -32 mA for high-level states. Propagation delays are specified with maximum values of 3.7 ns for LOW-to-HIGH transitions and 3.5 ns for HIGH-to-LOW transitions at the recommended operating conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features IOFF circuitry that disables outputs during partial power-down mode to prevent potentially damaging backflow currents.
• Includes power-up 3-state functionality to ensure safe initialization upon application of supply voltage.
• Provides latch-up protection exceeding 500 mA per JESD78B Class II Level A standards.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring isolation of powered-down sections.
• High-speed 16-bit bus interface systems.
• Direct interfacing with TTL level logic circuits.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against current Nexperia documentation, as revision history indicates changes to available packages. Confirm the component status, as older suffixes may be superseded by newer versions or removed from production lines. Ensure design compatibility with the latest ESD specifications defined in the most recent product data sheet.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed inversion with significant drive strength. The multiple VCC and GND pins help minimize switching noise in dense layouts. Verify that the system operates strictly within the 4.5 V to 5.5 V supply range to maintain specified timing characteristics and avoid exceeding absolute maximum ratings.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT16240A family of 16-bit buffers. Revision 9 of the datasheet notes that the SSOP48 package (SOT370-1) was removed in version 7, making the TSSOP48 (SOT362-1) the primary plastic package option. The manufacturer is Nexperia B.V., which acquired the NXP standard products business.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ABT16240ADGG variant if a TSSOP48 package is required instead of the legacy SSOP form factor. Verify functional equivalence with other 16-bit ABT series inverters if pinout compatibility allows.
