SN74ABT2244N

Buffers, Drivers, Receivers, Transceivers Overview

The SN74ABT2244N is an octal buffer and line driver manufactured by Texas Instruments, belonging to the ABT logic series. It features eight input lines and eight output lines with inverting polarity. The device utilizes a PDIP-20 package for through-hole mounting. Electrical specifications include a high-level output current of -32 mA and a low-level output current of 15 mA. The operating supply voltage range spans from 4.5 V to 5.5 V, with a maximum operating temperature of +85 C and a minimum of -40 C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides tri-state outputs for bus-oriented memory and circuit driving applications
• Features inverting polarity for signal inversion within digital logic circuits
• Supports through-hole installation via a standard PDIP-20 package

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory driving
• Clock drivers
• Buffering applications requiring signal inversion

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-20 through-hole package variant when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the inverting logic function aligns with the design requirements, distinguishing it from non-inverting counterparts like the SN74ABT244N. Cross-reference the manufacturer part number against distributor catalogs to ensure accurate component identification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with tri-state capability is required for 5V logic systems. The ABT series offers faster switching speeds compared to standard TTL or HC families. Consider the PDIP-20 package constraints if PCB layout requires through-hole technology. Verify that the 15 mA low-level output current meets the load requirements of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the SN74ABT2244A family of octal buffers and line drivers. It serves as the inverting counterpart to the SN74ABT244A series. Both share similar electrical characteristics and packaging options but differ in logical polarity. The ABT series is designed for high-speed applications within the 5V logic domain.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ABT244AN is a functional substitute if inverting polarity is not required. Other ABT series octal buffers may serve as alternatives depending on specific speed and drive current needs.
