74AHC244D-Q100,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHC244D-Q100,118 is an octal buffer and line driver featuring three-state outputs, housed in a 20-lead SO plastic small outline package (SOT163-1). 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 four-bit buffers controlled by separate active-low output enable inputs (1OE and 2OE). Inputs are overvoltage tolerant up to 5.5 V, facilitating use as level translators in mixed-voltage environments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when automotive reliability is required alongside wide supply voltage flexibility. The 74AHC244D-Q100 variant specifically utilizes CMOS input levels, distinguishing it from the AHCT counterpart which uses TTL levels. Ensure the design accommodates the specified temperature range and power dissipation derating curves for the SO20 package.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHC244-Q100 family of octal buffers. It shares functional characteristics with other packages in the series, such as TSSOP20 and DHVQFN20, but differs in physical dimensions and thermal properties. The 'D' designation specifically identifies the SO20 plastic small outline package configuration.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the 74AHCT244D-Q100,118, though input logic levels differ. Non-automotive equivalents like the standard 74AHC244D lack AEC-Q100 qualification.
