74AHCT244D-Q100,11

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT244D-Q100,11 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 2.0 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device contains two independent output enable inputs (1OE and 2OE), each controlling four outputs. Inputs are overvoltage tolerant up to 5.5 V, enabling use in mixed-voltage environments. The component meets AEC-Q100 Grade 1 qualification standards for automotive applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required package type, as the base part number covers multiple options. Confirm that the Q100 designation aligns with automotive reliability requirements. Ensure the D suffix corresponds to the SO20 plastic small outline package variant. Cross-reference the manufacturer's latest documentation for any updates to pinning or electrical characteristics before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state capability is required for automotive logic interfaces. The AHCT series ensures TTL input levels while maintaining CMOS performance. Verify that the operating temperature range extends to +125 °C if high-temperature environments are anticipated. Consider the overvoltage tolerance feature if interfacing with 5.5 V signals while powered by lower voltages.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the Nexperia 74AHC(A)HCT244-Q100 family of octal buffers. It shares functional similarities with other members like the 74AHC244PW-Q100 but differs in package configuration. The D suffix specifically denotes the SO20 package, distinguishing it from TSSOP or DHVQFN variants within the same logical family.
