74LVCH16244AEV/G;5

Overview

The Nexperia 74LVCH16244AEV/G,5 is a 16-bit buffer/line driver with 3-state outputs. It supports a supply voltage range of 1.2 V to 3.6 V and features 5 V tolerant inputs and outputs for interfacing with 5 V logic. The device includes IOFF circuitry for partial power-down mode operation and bus hold on all data inputs. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerant inputs and outputs for direct interfacing with 5 V logic systems.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during partial power-down.
• Integrates bus hold functionality on all data inputs to eliminate the need for external pull-up resistors.

Applications

• Mixed 3.3 V and 5 V environments
• Partial power-down applications
• Buffering and line driving

Procurement Notes

Verify the specific suffix 'EV' against the official datasheet, as revision history indicates this package type was removed in version 15. Confirm current production status directly with Nexperia or authorized distributors, as availability may be limited or discontinued.

Selection Notes

Select this component when a 16-bit buffer with 5 V tolerance and bus hold is required. Ensure the design accommodates the specified operating temperature range and utilizes the IOFF feature if partial power-down functionality is necessary for the application.

Part Context

This part belongs to the 74LVC/LVCH family of high-speed CMOS logic devices. It functions as a non-inverting buffer/line driver, distinct from transceivers which include direction control. The device is designed for low power consumption and high noise immunity in digital signal processing applications.

Replacement Considerations

Check for equivalents such as 74LVCH16244ADGG or 74LVCH16244ADGV. Verify pinout compatibility and ensure the replacement package matches the board layout requirements.
