SN74AS244ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS244ANSR is an octal buffer and line driver from the Texas Instruments AS logic series, housed in a 20-pin SOIC package. It features non-inverting, three-state outputs with bipolar technology. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum operating current of 24 uA. Electrical characteristics include a high-level output current of -15 mA and a low-level output current of 64 mA. Propagation delay is specified at 6.2 ns. It supports surface-mount installation and functions reliably between 0°C and +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ANSR' corresponds to the SOIC-20 package and tape-and-reel delivery format. Confirm RoHS compliance status through official manufacturer documentation or certified distributor declarations. Ensure the component meets the required industrial temperature range specifications for the intended application environment before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed operation is critical, as the AS series offers faster propagation delays compared to standard LS or HC logic families. Consider the bipolar construction for robust drive capability, specifically the higher low-level sink current. Evaluate the 20-pin SOIC footprint against available PCB space constraints and thermal management requirements for surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AS244A family of octal buffers and drivers. It shares functional similarities with other 74-series logic devices but distinguishes itself through superior speed characteristics inherent to the Advanced Schottky (AS) technology. The device serves as a direct replacement for older high-speed logic components in legacy designs requiring enhanced switching performance.
