74LVC16244ADL,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVC16244ADL,112 is a 16-bit buffer and line driver featuring 3-state outputs. It operates within a supply voltage range of 1.2 V to 3.6 V and provides 5 V tolerant inputs and outputs for interfacing with 5 V logic systems. The device includes four independent output enables (1OE, 2OE, 3OE, 4OE) controlling groups of four outputs each. Inputs utilize Schmitt-trigger action to tolerate slow rise and fall times. The component supports partial power-down applications via IOFF circuitry, which disables outputs to prevent backflow current when powered down.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features 5 V tolerant inputs and outputs for direct interfacing with 5 V logic devices in mixed voltage environments.
• Includes IOFF circuitry that disables outputs during partial power-down to prevent potentially damaging backflow currents.
• Utilizes Schmitt-trigger action at all data inputs to ensure tolerance for slower input signal transition rates.
• Provides low inductance multiple power and ground pins designed to minimize noise and ground bounce effects.

Buffers, Drivers, Receivers, Transceivers Applications

• Buffering and driving signals in mixed 3.3 V and 5 V logic environments
• Line driving applications requiring high-impedance isolation capabilities
• Partial power-down system configurations utilizing IOFF functionality

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the ordering information table, as the ADL suffix historically indicated SSOP48 but was removed from the latest datasheet revision. Confirm the temperature range requirement matches the -40 °C to +125 °C specification. Ensure the design accounts for the 5 V input/output tolerance limits defined in the recommended operating conditions. Check for any recent product status changes or obsolescence notices directly from the manufacturer before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit non-inverting buffer with 3-state control is required for 5 V tolerant interfaces. The LVC series offers CMOS low power consumption suitable for battery-operated applications. Consider the available package options such as TSSOP48 if the original SSOP variant is unavailable. Verify that the application does not require automotive qualification, as standard products lack specific automotive testing.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74LVC16244A family of 16-bit buffers and line drivers. The family includes variants like the 74LVCH16244A which adds bus hold functionality on data inputs. These components are designed for multibyte flow-through architectures and provide high-impedance states when VCC is zero. The series complies with various JEDEC standards covering different voltage ranges from 1.65 V to 3.6 V.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74LVCH16244ADGG serves as a functional substitute offering identical electrical characteristics with the addition of bus hold circuits on data inputs. Both parts share the same 16-bit buffer architecture and 5 V tolerance specifications. Designers must verify pin compatibility and package dimensions when swapping between these variants.
