74LV244D-Q100J

Overview

The 74LV244D-Q100 is an octal buffer and line driver featuring three-state outputs, manufactured by Nexperia. It operates within a supply voltage range of 1.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device includes two output enable inputs (1OE and 2OE), each controlling four outputs. It accepts TTL input levels between VCC = 2.7 V and VCC = 3.6 V. ESD protection exceeds 2000 V for Human Body Model and 1000 V for Charge Device Model. Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 Grade 1 standard
• Wide supply voltage range supporting low voltage applications from 1.0 V to 5.5 V
• High latch-up immunity exceeding 100 mA per JESD 78 Class II Level B
• Robust electrostatic discharge protection meeting JEDEC standards

Applications

• Automotive electronic systems requiring AEC-Q100 Grade 1 compliance
• Bus-oriented memory and data transmission interfaces
• Clock drivers and buffer circuits in low-voltage environments

Procurement Notes

Verify the specific package variant against project requirements, as the D suffix denotes SO20 while PW denotes TSSOP20. Confirm that the -Q100 designation aligns with automotive qualification needs. Ensure the operating temperature range of -40 °C to +125 °C matches the environmental constraints of the final assembly. Cross-reference the latest datasheet revision to confirm static and dynamic characteristics have not changed since initial design approval.

Selection Notes

Select this component when an octal buffer with independent control over two groups of four outputs is required. The dual output enables allow flexible configuration for bus driving or isolated signal buffering. Consider the wide supply voltage compatibility if interfacing with mixed-voltage logic families. The CMOS construction ensures low power dissipation, making it suitable for battery-operated or energy-efficient designs.

Part Context

This part belongs to the 74LV series of low-voltage CMOS logic devices produced by Nexperia. The LV series is optimized for operation down to 1.0 V, bridging the gap between traditional 5 V logic and modern low-voltage systems. The Q100 suffix indicates automotive-grade qualification, distinguishing it from standard commercial variants which may have different reliability or testing criteria.

Replacement Considerations

The 74LV244PW-Q100 serves as a pin-compatible alternative in a TSSOP20 package. Verify thermal derating curves and physical dimensions before substituting packages. Ensure any replacement maintains the same AEC-Q100 Grade 1 qualification status.
