74LVCH16245AEV-Q1Y

Overview

The Nexperia 74LVCH16245AEV-Q1Y is a 16-bit bus transceiver with 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It supports a supply voltage range of 1.2 V to 3.6 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger inputs, IOFF circuitry for partial power-down protection, and bus hold functionality on data inputs. It operates within an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1) standards
• IOFF circuitry prevents damaging backflow current during partial power-down
• Bus hold feature on all data inputs eliminates the need for external pull-up resistors

Applications

• Mixed 3.3 V and 5 V environments requiring level translation
• Automotive electronic systems requiring Grade 1 qualification
• Applications utilizing partial power-down modes

Procurement Notes

Verify that the specific suffix Q1Y corresponds to the intended package variant, as the official datasheet lists ADGG (TSSOP48) and ADGV (TVSOP48). Confirm the component meets AEC-Q100 Grade 1 requirements for your target automotive application. Ensure design safeguards are implemented to prevent operation beyond the specified absolute maximum ratings.

Selection Notes

Select this component when a 16-bit bi-directional translator is required for mixed-voltage logic interfaces. The LVCH variant provides bus hold capabilities not present in the standard LVC version. Verify compatibility with the system's operating voltage range between 1.2 V and 3.6 V and ensure the thermal environment remains within the specified -40 °C to +125 °C limits.

Part Context

This part belongs to the Nexperia 74LVC/LVCH16245A-Q100 family of 16-bit bus transceivers. The family offers configurations for both standard LVC and low-voltage CMOS H (LVCH) technologies. These devices utilize a MULTIBYTE flow-through architecture and are designed for high-speed data transmission in automotive and industrial environments.

Replacement Considerations

The official datasheet revision history indicates that the AEV package type was removed from production. Consider substituting with the 74LVCH16245ADGG-Q100 or 74LVCH16245ADGV-Q100 variants which are currently listed in the ordering information.
