74LVC16244ADGG-Q1J

Overview

The Nexperia 74LVC16244ADGG-Q1J is a 16-bit buffer and line driver featuring 3-state outputs, designed for automotive applications. 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 for partial power-down mode operation and Schmitt-trigger action on all inputs to tolerate slower rise and fall times. It is qualified to AEC-Q100 Grade 1 standards and supports temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) for use in automotive environments
• IOFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow current
• Schmitt-trigger inputs provide tolerance for slower input rise and fall times
• Bus hold functionality on data inputs eliminates the need for external pull-up resistors

Applications

• Mixed 3.3 V and 5 V logic environments requiring level translation
• Partial power-down applications utilizing IOFF circuitry
• Automotive electronic systems requiring AEC-Q100 Grade 1 compliance

Procurement Notes

Verify that the specific suffix Q1J corresponds to the Automotive Electronics Council (AEC) standard Q100 Grade 1 qualification as documented in the official product data sheet. Confirm package type matches SOT362-1 (TSSOP48). Ensure design safeguards are implemented to minimize risks associated with application-specific designs, as Nexperia accepts no liability for default or damage based on customer application weaknesses.

Selection Notes

Select this component when a 16-bit buffer with 3-state outputs is required for automotive-grade reliability. It is suitable for translating signals between 3.3 V and 5 V logic families due to its 5 V tolerant I/O capabilities. The inclusion of bus hold features simplifies design by removing the need for external pull-up resistors on unused inputs. Verify that the operating temperature range meets the specific environmental requirements of the target application.

Part Context

This part belongs to the 74LVC/LVCH16244A-Q100 family of 16-bit buffers and line drivers manufactured by Nexperia. The device is available in TSSOP48 (SOT362-1) and TVSOP48 (SOT480-1) packages. It shares functional characteristics with other members of the LVC series but is specifically qualified for automotive use under the AEC-Q100 standard, distinguishing it from standard commercial grade variants.
