Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the component meets RoHS compliance standards and lead-free manufacturing requirements as specified in the official datasheet before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.65 V and 3.6 V. It is suitable for applications needing high-speed data transfer with reduced power consumption compared to standard CMOS logic families. Ensure the design accommodates the 20-pin SOIC footprint and thermal characteristics.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ALVCH244 series of octal buffers and line drivers. It is distinct from other variants like SN74AHC244 or SN74LVC244 due to its specific low-voltage high-speed technology optimized for 3.3-V systems while maintaining compatibility with lower voltage domains.

Buffers, Drivers, Receivers, Transceivers FAQ

What is the control logic for the enable pin?

The enable input is active-low, meaning the outputs are enabled when the signal is low and placed in a high-impedance state when high.

Is the SN74ALVCH244DWR bidirectional?

Yes, the device supports bidirectional data transmission, allowing data flow in either direction depending on the configuration.
