74AC11244PW

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments SN74AC11244PW is an octal buffer and line driver featuring three-state outputs, housed in a TSSOP-24 package. It operates within a supply voltage range of 3 V to 5.5 V, with a maximum operating current of 80 µA and static current of 8 µA. The device provides high-level output currents up to -24 mA and low-level output currents of 24 mA. It supports non-inverting logic across eight input and eight output lines, functioning reliably at temperatures from -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffer channels for signal distribution.
• Three-state output capability allowing multiple drivers to share bus lines without interference.
• CMOS construction designed for high-speed performance and improved density in memory address applications.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

This component is scheduled for obsolescence and will be discontinued by the manufacturer. Verify end-of-life status before finalizing designs. Ensure alternative sourcing strategies are in place due to limited future availability. Confirm RoHS compliance details directly with authorized distributors as specifications may vary by production batch.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring octal buffering with three-state control in a compact TSSOP-24 footprint. It is suitable for systems operating between 3 V and 5.5 V where moderate drive strength is sufficient. Consider pin-compatible alternatives if long-term supply stability is required, as this specific package variant is being phased out.

Buffers, Drivers, Receivers, Transceivers Part Context

The SN74AC11244 series belongs to Texas Instruments' AC logic family, offering higher speed than standard 74LS devices while maintaining CMOS power efficiency. This specific PW variant utilizes a plastic small-outline dual-in-line surface-mount package, distinguishing it from tape-and-reel or SOIC equivalents within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitute part numbers include 74AC11244PWR (tape and reel version) and 74ACT11244PW (ACT series variant). Verify voltage compatibility when switching between AC and ACT families.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the logic polarity of the SN74AC11244PW?

The device features non-inverting logic, meaning the output state follows the input state directly.

Does the SN74AC11244PW support bidirectional data flow?

No, it is designed as a buffer/driver with unidirectional signal flow from inputs to outputs.
