74AHCT244D,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT244D,112 is an octal buffer and line driver featuring three-state outputs. It belongs to the AHCT logic series, designed for operation with a supply voltage range of 4.5 V to 5.5 V. The device provides eight non-inverting inputs and corresponding outputs, configurable as two four-bit buffers or one eight-bit buffer. It utilizes a SOIC-20 surface-mount package. Key electrical characteristics include a maximum propagation delay of 15 ns, high-level output current of -8 mA, low-level output current of 8 mA, and static current of 4 µA. It operates within a temperature range of -40 °C to +125 °C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '112' against the manufacturer's official datasheet to confirm the tape and reel packaging configuration. Confirm that the SOIC-20 package variant matches your PCB footprint requirements. Ensure the AEC-Q100 qualification status aligns with your automotive application needs if applicable, as this may vary by specific production batch or sub-part number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance. The AHCT series bridges the gap between standard HC logic and TTL inputs. Verify that the 4.5 V to 5.5 V supply range suits the system power rails. Consider the SOIC-20 package dimensions for thermal management and board space constraints compared to TSSOP alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the Nexperia 74AHCT244 family of octal buffers. It shares functional similarities with the 74AHC244 but differs in input threshold specifications to support TTL interfaces. The 'D' designation indicates the SOIC-20 package, while '112' typically denotes the specific packaging quantity and reel type defined by the manufacturer.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74AHCT244PW,112 serves as a pin-compatible alternative using a TSSOP-20 package instead of SOIC-20. For automotive applications, the 74AHCT244D-Q100,11 offers qualified reliability under AEC-Q100 standards.
