74LVCH16244ADGV-QJ

Overview

The Nexperia 74LVCH16244ADGV-QJ is a 16-bit buffer/line driver with 3-state outputs, qualified to AEC-Q100 Grade 1. It operates on 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 data inputs. It utilizes a TVSOP48 (SOT480-1) package.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• Bus hold functionality on all data inputs
• IOFF circuitry prevents backflow current during power-down
• Direct interface capability with TTL levels

Applications

• Automotive electronic systems
• Mixed 3.3 V and 5 V logic environments
• Partial power-down applications

Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the automotive grade qualification aligns with project requirements. Ensure input voltage tolerances are compatible with the target system logic levels before finalizing procurement specifications.

Selection Notes

Select this component when a 16-bit buffer with 5 V tolerance is required for automotive or industrial applications. The LVCH series offers Schmitt-trigger action for slower input transitions. Verify that the TVSOP48 package dimensions fit the PCB layout constraints and thermal dissipation needs.

Part Context

This part belongs to the Nexperia 74LVC/LVCH 16244A-Q100 family of 16-bit buffers. The 'LVCH' designation indicates low-voltage CMOS technology with Schmitt-trigger inputs. The '-QJ' suffix typically denotes specific packaging or tape-and-reel configurations within the automotive product line.

Replacement Considerations

The 74LVC16244ADGV-Q100 is a non-Schmitt-trigger variant within the same family. Cross-reference pinouts and electrical characteristics carefully when substituting.
