74LVCH16244ADGG,51

Overview

The Nexperia 74LVCH16244ADGG,51 is a 16-bit buffer and line driver featuring Schmitt-trigger inputs and three-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 IOFF circuitry to prevent backflow current during partial power-down states. Data inputs feature bus hold functionality to eliminate the need for external pull-up resistors. It is housed in a 48-lead TSSOP plastic thin shrink small outline package (SOT362-1) and supports an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Provides 5 V tolerant inputs and outputs for direct interfacing with 5 V logic devices.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow currents when powered down.
• Features Schmitt-trigger action on all inputs to ensure tolerance against slow input rise and fall times.
• Integrates bus hold circuits on data inputs to maintain stable logic levels without external components.

Applications

• Translating signals between mixed 3.3 V and 5 V environments
• Buffering and driving high-capacitance or long transmission lines
• Partial power-down mode applications requiring isolation

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm compliance with RoHS and REACH regulations as stated in the product documentation. Ensure the selected component aligns with the specified SOT362-1 package dimensions for PCB layout compatibility.

Selection Notes

Select this component when designing systems requiring 16-bit buffering with 5 V tolerance. Consider the LVCH series for its low power consumption and wide supply voltage range. Verify that the application environment falls within the specified -40 °C to +125 °C operating temperature limits.

Part Context

This part belongs to the Nexperia 74LVC/LVCH family of high-speed CMOS logic devices. It serves as a non-inverting buffer/line driver designed for robust signal integrity in digital systems. The device is manufactured by Nexperia USA Inc. and is available in production status.

Replacement Considerations

The 74LVC16244ADGG,51 is functionally equivalent to the 74LVC16244ADGG variant within the same package and electrical specifications. Verify pinout and electrical characteristics before substituting.
