74LVC16244AEV,157

Overview

The Nexperia 74LVC16244AEV,157 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 for partial power-down mode operation, preventing damaging backflow currents. Inputs utilize Schmitt-trigger action for tolerance to slow rise and fall times. The component operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerant input/output capabilities for direct interfacing with 5 V logic devices.
• Features IOFF circuitry that disables outputs during partial power-down to prevent backflow current.
• Incorporates Schmitt-trigger action at all inputs to ensure tolerance for slower signal transition rates.

Applications

• Mixed 3.3 V and 5 V environment translation
• Partial power-down system applications
• Buffering for high-speed data buses

Procurement Notes

Verify the specific package type against the required PCB footprint, as the datasheet lists TSSOP48 and TVSOP48 variants. Confirm the exact ordering code suffix matches the desired configuration. Check the latest product status on the manufacturer website to ensure availability and confirm compliance with relevant environmental directives such as RoHS before finalizing procurement.

Selection Notes

Select this component when a 16-bit buffer with 3-state control is required in mixed-voltage designs. Ensure the operating voltage falls within the 1.2 V to 3.6 V range. Consider the IOFF feature if the application requires protection against backflow during power-down states. Verify thermal management requirements based on the selected package and ambient temperature conditions.

Part Context

This part belongs to the 74LVC16244A family of 16-bit buffers and line drivers manufactured by Nexperia. The LVC series is designed for low-voltage CMOS applications. The device architecture allows configuration as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer using dedicated output enable pins.

Replacement Considerations

The 74LVCH16244A is a related variant within the same family offering bus hold functionality on data inputs. Other packages such as TSSOP48 (ADGG) and TVSOP48 (ADGV) are available within the same logical specification.
