74HC244BQ-Q100,115

Overview

The Nexperia 74HC244BQ-Q100,115 is an octal buffer and line driver with three-state outputs, qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features non-inverting logic with two independent output enable inputs (1OE and 2OE), each controlling four outputs. It utilizes a DHVQFN20 package (SOT764-1) measuring 2.5 mm by 4.5 mm.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Wide supply voltage range supporting operation from 2.0 V to 6.0 V
• High noise immunity with CMOS low power dissipation characteristics
• DHVQFN package with side-wettable flanks enabling automated optical inspection

Applications

• Octal bus interface systems
• Automotive electronic circuits
• Mixed voltage environment translation

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm that the component meets the AEC-Q100 Grade 1 requirements for your target application. Ensure design compatibility with the DHVQFN20 footprint and thermal pad handling specifications provided in the datasheet.

Selection Notes

Select this component when an octal buffer with three-state control is required for automotive or industrial environments. It is suitable for designs needing wide voltage tolerance and high noise immunity. Consider the DHVQFN20 package constraints regarding thermal dissipation and soldering profiles during PCB layout.

Part Context

This part belongs to the Nexperia 74HC244-Q100 family of octal buffers. It shares functional similarities with other 74HC series devices but is specifically optimized for automotive reliability. The BQ suffix indicates the DHVQFN20 leadless package variant, distinguishing it from SO20 or TSSOP20 versions.

Replacement Considerations

Direct replacements include other 74HC244 variants from Nexperia such as the 74HC244D-Q100 or 74HC244PW-Q100, provided the package type difference is accommodated. Cross-family substitutes like 74AHC244 may offer different speed or voltage characteristics.
