SN74AS244AN

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS244AN is an octal buffer and line driver from the Texas Instruments AS logic series. It features eight non-inverting inputs with three-state outputs, housed in a 20-pin PDIP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 6.2 ns, a high-level output current of -15 mA, and a low-level output current of 64 mA. It supports through-hole mounting and functions within a temperature range of 0°C to +70°C.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and environmental compliance. Ensure the ordering code matches the required PDIP-20 configuration. Cross-reference manufacturer part numbers to avoid confusion with similar variants like the SN74AS244ADWRE4 which uses a different package. Confirm RoHS status via the manufacturer's documentation before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed operation and strong low-level drive capability are required. The AS series offers faster propagation delays compared to standard TTL or HC families. Consider the PDIP-20 package for through-hole prototyping or legacy board designs. Evaluate power consumption requirements as bipolar logic typically draws more quiescent current than CMOS alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74AS244A family of octal buffers and line drivers. It is designed for high-speed digital applications where fast switching speeds are critical. The AS (Advanced Schottky) logic family provides a balance between speed and power dissipation, making it suitable for demanding digital systems.
