74AC11244NT

Buffers, Drivers, Receivers, Transceivers Overview

The Texas Instruments 74AC11244NT is an octal buffer and line driver featuring three-state outputs, manufactured using the EPIC 1-μm CMOS process. It operates within a supply voltage range of 3 V to 5.5 V and supports an operating temperature from –40°C to 85°C. The device provides high-level output currents up to –24 mA and low-level currents up to 24 mA at 5.5 V. Propagation delays are characterized at 6.7 ns maximum (tPLH) and 6.9 ns maximum (tPHL) at 5 V. It utilizes a flow-through architecture and includes center-pin VCC and GND configurations.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package designation 'NT' corresponds to the Standard Plastic DIP configuration in official documentation. Confirm that the component meets the required electrical specifications for your target operating voltage and temperature range before procurement. Ensure all unused inputs are properly terminated to VCC or GND to maintain operational integrity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state control is required for high-density PCB layouts. The flow-through architecture facilitates efficient routing compared to standard buffered designs. Verify compatibility with system logic levels and ensure the power supply voltage remains within the specified 3 V to 5.5 V range for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AC logic family, utilizing Texas Instruments' Enhanced-Performance Implanted CMOS (EPIC) technology. It serves as an octal version of single-buffer logic families, providing eight independent non-inverting buffers. The NT suffix specifically denotes the standard plastic dual in-line package option available for this series.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Consult official datasheets for equivalent octal buffers with three-state outputs. Verify pinout compatibility and electrical characteristics such as propagation delay and output current drive capabilities against alternative part numbers.
