SN74ABT244AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT244AN is an octal buffer and line driver from the Texas Instruments ABT logic series. It features eight non-inverting inputs driving three-state outputs in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a maximum propagation delay of 4.3 ns. It supports high-level output currents of -32 mA and low-level output currents of 64 mA. The component functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AN' corresponds to the 20-pin PDIP package when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors, as environmental declarations may vary by production batch. Ensure the supplier provides valid traceability for this Texas Instruments part number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high drive capability and fast switching speeds at 5V logic levels. The ABT series offers superior performance compared to standard 74LS devices. Consider the PDIP-20 form factor for through-hole prototyping or legacy board designs where surface-mount options are not feasible.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT244A family of octal buffers. It shares functional similarities with other 244-series devices but distinguishes itself through ABT BiCMOS technology, which delivers higher speed and stronger drive currents than CMOS or LS counterparts. It serves as a direct replacement for older 74F244 designs in high-performance digital systems.
