74ABT16240ADGG,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT16240ADGG,112 is a 16-bit inverting buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an output drive capability of +64 mA for low-level states and -32 mA for high-level states. The device includes IOFF circuitry to prevent backflow current during partial power-down conditions. It utilizes BiCMOS technology for high-speed performance and direct interface with TTL levels. The component is housed in a 48-lead TSSOP package (SOT362-1) and functions reliably across an ambient temperature range from -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent output enables controlling groups of 3-state outputs.
• Includes IOFF circuitry to disable outputs and prevent damaging backflow currents when powered down.
• Provides latch-up protection exceeding 500 mA per JESD78B Class II Level A standards.
• Supports live insertion and extraction operations without system damage.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down applications requiring isolation of powered-down buses.
• High-speed 16-bit bus interface systems.
• Direct interfacing between logic circuits operating at different voltage levels.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix ADGG,112 against official Nexperia documentation to confirm the TSSOP48 package type and lead-free status. Ensure that the required operating temperature range aligns with the specified -40 °C to +85 °C limits. Confirm that the application design accounts for the multiple VCC and GND pins necessary to minimize switching noise effectively.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-drive current capabilities on 16-bit data lines. The inclusion of IOFF functionality makes it suitable for systems needing safe partial power-down modes. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V window to maintain signal integrity and prevent device stress.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT16240A family of 16-bit inverting buffers. It is manufactured by Nexperia USA Inc. and is distinct from similar devices like the 74ABT16244 due to its inverting logic function. The ADGG,112 designation specifically identifies the thin shrink small outline plastic package variant.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct substitutes such as the 74ABT16240ADL if SSOP packaging is acceptable. Verify functional compatibility regarding pinout and electrical characteristics before swapping components.
