74ABT16244ADGG,512

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT16244ADGG,512 is a 16-bit 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 typical values of 1.7 ns for LOW-to-HIGH transitions and 2.1 ns for HIGH-to-LOW transitions at 5.0 V. It utilizes BiCMOS technology and includes IOFF circuitry to prevent backflow current during partial power-down conditions.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent output enable controls (1OE through 4OE) allowing segmentation into four 4-bit buffers or two 8-bit buffers.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents when the device is powered down.
• Supports live insertion and extraction operations without causing system interference.
• Provides direct interface compatibility with TTL logic levels.

Buffers, Drivers, Receivers, Transceivers Applications

• High-speed 16-bit bus interface systems
• Partial power-down mode applications requiring leakage prevention
• Live insertion and extraction peripheral connections

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature range. Confirm that the component status aligns with current production requirements. Ensure design specifications account for the absolute maximum ratings regarding input and output voltages to prevent permanent damage. Cross-reference the latest datasheet revision for any updates to ESD protection classifications or functional descriptions before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with significant drive strength in a 5 V environment. The multiple VCC and GND pins help minimize switching noise compared to single-supply alternatives. Consider the four separate output enables if the application requires granular control over data flow segments rather than a single global enable signal.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ABT16244A family of 16-bit buffers. It is housed in a TSSOP48 plastic thin shrink small outline package (SOT362-1). The device is manufactured by Nexperia and is designed for operation across an ambient temperature range of -40 °C to +85 °C.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ABT16244ADL variant which uses an SSOP48 package. Verify pinout compatibility if substituting between different package types within the same logical family.

Buffers, Drivers, Receivers, Transceivers FAQ

How does the device handle partial power-down scenarios?

The integrated IOFF circuitry automatically disables the outputs when the device is powered down, preventing potentially damaging backflow current through the component.

What is the configuration flexibility of the outputs?

The 16 outputs can be configured as one 16-bit buffer, two 8-bit buffers, or four 4-bit buffers using the four dedicated output enable inputs.
