74ABT16240ADL,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74ABT16240ADL,112 is a 16-bit inverting buffer and line driver featuring 3-state outputs. It utilizes BiCMOS technology to deliver high speed and robust output drive capabilities. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports direct interfacing with TTL levels. It includes IOFF circuitry for partial power-down applications, preventing backflow current when powered down. The component provides latch-up protection exceeding 500 mA per JESD78B Class II Level A standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features four independent output enables (1OE, 2OE, 3OE, 4OE) controlling groups of four 3-state outputs each.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down states.
• Provides power-up 3-state functionality to ensure safe initialization upon application of supply voltage.
• Supports live insertion and extraction operations without causing system interference.

Buffers, Drivers, Receivers, Transceivers Applications

• Partial power-down bus interface systems requiring isolation during low-power modes
• High-speed data buffering for 16-bit parallel buses
• Line driving applications requiring TTL level compatibility

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the datasheet revision history. The 'DL' suffix indicates an SSOP-48 package which was removed from the standard product data sheet in revision 7 (July 2021). Confirm if the ordered part corresponds to the legacy SOT370-1 specification or if it has been superseded by the TSSOP48 (SOT362-1) variant listed in current documentation. Ensure compliance with the latest RoHS directives.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring 16-bit inverting buffering with 3-state control on a single IC. It is suitable for 5 V logic systems needing high drive strength and fast switching speeds. Consider the multiple ground and VCC pins for noise reduction in dense PCB layouts. Verify that the required operating temperature range of -40 °C to +85 °C meets the environmental constraints of the target application.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74ABT logic family, which employs Advanced BiCMOS Technology. This technology combines the high speed of bipolar transistors with the low power consumption of CMOS. The 74ABT series is designed for high-performance digital applications where signal integrity and propagation delay are critical factors in system design.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ABT16240ADGG variant, which uses a TSSOP48 package (SOT362-1). The original DL package (SSOP48) was removed from the active product data sheet in July 2021. Ensure pinout compatibility between the legacy SSOP and the current TSSOP form factor before substitution.
