74LVC16244AEV,151

Overview

The Nexperia 74LVC16244AEV,151 is a 16-bit buffer and line driver featuring 3-state outputs. It supports a wide supply voltage range from 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 IOFF circuitry to prevent backflow current during partial power-down states. Inputs utilize Schmitt-trigger action for noise immunity. The component operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerant input/output capability for mixed-voltage system interfacing
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current when powered down
• Features Schmitt-trigger inputs to ensure tolerance against slow rise and fall times
• Offers high-impedance output state when the supply voltage (VCC) is zero

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down mode operation in portable electronics
• Buffering data lines in low-power CMOS applications

Procurement Notes

Verify the specific package type and suffix against the official Nexperia datasheet before ordering. Confirm that the selected variant matches the required operating temperature range and pin configuration. Ensure design compliance with the absolute maximum ratings provided in the product documentation to avoid permanent damage.

Selection Notes

Select this component for designs requiring 16-bit buffering with 5 V tolerance. Consider the 74LVCH16244A variant if bus hold functionality on all data inputs is required. Verify that the chosen package option meets the PCB layout constraints and thermal requirements of the target application.

Part Context

This part belongs to the Nexperia LVC/LVCH family of logic ICs. These devices are designed for low-power consumption and direct interface with TTL levels. The family supports various package options including TSSOP and TVSOP formats, providing flexibility for different board space and lead pitch requirements in consumer and industrial electronics.

Replacement Considerations

The 74LVCH16244A is a related variant within the same family. Note that the LVCH version includes bus hold circuitry on data inputs, which the standard LVC version lacks. Verify functional equivalence regarding the absence or presence of bus hold features when substituting.
