SN74LV244ARGYR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV244ARGYR is an octal buffer and line driver manufactured by Texas Instruments, belonging to the LV (Low Voltage) logic family. It features eight non-inverting buffers organized into two independent four-bit groups, each with its own output enable control. The device operates within a supply voltage range of 2 V to 5.5 V and supports mixed-mode operation across all ports. It utilizes a 20-pin VQFN package designed for surface-mount applications.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports mixed-mode voltage operation allowing simultaneous use of different input and output voltage levels on separate ports.
• Includes Ioff circuitry to prevent excessive current draw when the device is powered down while connected to active buses.
• Features enhanced latch-up performance exceeding specified industry standards for robustness in high-noise environments.

Buffers, Drivers, Receivers, Transceivers Applications

• Memory address drivers for high-density storage systems
• Clock signal distribution in digital circuits
• Bus-oriented receivers and transmitters

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ARGYR' against the manufacturer's official datasheet to confirm the exact package dimensions and tape-and-reel specifications. Ensure compatibility with the target PCB footprint and reflow soldering profile requirements for the VQFN-20 package before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring wide voltage flexibility between 2 V and 5.5 V. It is suitable for replacing older 5 V logic families where lower power consumption and mixed-voltage interface capabilities are required. Verify that the 3-state output characteristics meet the bus load requirements of the system.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LV244A series of octal buffers and drivers. The series is engineered to improve density and performance for three-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. It represents a low-voltage CMOS technology solution for general-purpose digital buffering.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74LV244ADWR or SN74LV244APWR if the VQFN package is unavailable. Ensure any substitute maintains the same 2 V to 5.5 V operating range and 3-state output functionality.
