74AC11244PWR

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74AC11244PWR is an octal buffer and line driver belonging to the AC logic series. It features eight non-inverting channels with three-state outputs housed in a 24-pin TSSOP package. The device operates within a supply voltage range of 3 V to 5.5 V, supporting high-level output currents of -24 mA and low-level output currents of 24 mA. Propagation delay is specified at 10.5 ns. It functions reliably across an operating temperature range of -40°C to +85°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Designed for CMOS compatibility with robust noise immunity and low static power consumption

Buffers, Drivers, Receivers, Transceivers Applications

• Clock distribution networks requiring signal regeneration
• Memory address and data bus buffering in computing systems
• General-purpose digital signal isolation and driving applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-24 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the design supports the 3V to 5.5V operating range. Check for end-of-life notices or alternative recommendations from Texas Instruments if long-term availability is required.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring octal buffering with three-state control in surface-mount designs. It serves as a suitable replacement for legacy 74FCT244 devices in compatible voltage environments. Consider the propagation delay characteristics for timing-critical paths. Verify that the load capacitance requirements align with the specified drive capabilities of the AC series.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74AC family of high-speed CMOS logic devices. The 74AC11244 specifically addresses the need for multiple buffered outputs in a single integrated circuit. It complements other octal drivers like the 74ACT11244, differing primarily in speed and voltage thresholds. The PWR suffix denotes the plastic small-outline thin package configuration.
