SN74AS244ANE4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS244ANE4 is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It belongs to the AS logic series and utilizes bipolar technology. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum low-level output current of 64 mA. It provides non-inverting signal transmission with two active-low output enable inputs. The component is housed in a standard plastic 20-pin DIP package and is characterized for operation over a temperature range of 0°C to 70°C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Octal configuration providing eight independent non-inverting buffers or line drivers
• Three-state outputs designed to drive bus lines or memory address registers
• PNP input structure reduces DC loading on driving circuits

• Memory address drivers
• Clock drivers
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix E4 confirms lead-free status and RoHS compliance as per manufacturer specifications. Confirm the N suffix corresponds to the standard plastic DIP-20 package variant. Ensure the SN74AS244A designation matches the required commercial temperature range of 0°C to 70°C rather than the military grade SN54AS244A.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance and reduced DC loading are required for bus applications. The AS series offers faster propagation delays compared to ALS variants. Verify that the 64 mA low-level output current capability meets the load requirements. Ensure the design accommodates the specific bipolar power consumption characteristics of the AS family.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the SN74AS244A octal buffer and line driver family from Texas Instruments. It shares functional similarities with the SN74ALS244C but utilizes bipolar technology for higher speed. The device is available in multiple package options including SOIC and ceramic packages, with the NE4 variant specifically denoting the plastic DIP format.
