SN74AS244ANG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74AS244ANG4 is an octal buffer and line driver from the Texas Instruments AS logic series. It features eight non-inverting outputs with three-state capability, 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 parameters 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 functions at temperatures between 0°C and +70°C with a quiescent current of 24 µA.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free status and RoHS compliance. Confirm the PDIP-20 package type matches the target board layout requirements. Ensure the operating temperature range meets the specific environmental conditions of the application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring high-speed buffering with significant drive strength. The AS series offers faster switching speeds compared to standard TTL or HC families. Consider the bipolar technology characteristics and power consumption profile relative to CMOS alternatives like the AHC or ACT series for similar functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the Texas Instruments 74AS244 family of octal buffers. The G4 suffix indicates a lead-free and RoHS-compliant version of the standard SN74AS244AN. It serves as a high-performance alternative to slower logic families, designed for applications demanding rapid signal transmission and reliable three-state control on digital buses.
