SN74S244DWG4

Buffers, Drivers, Receivers, Transceivers Overview

The SN74S244DWG4 is an octal buffer and line driver manufactured by Texas Instruments, featuring non-inverting logic with three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports input levels compatible with TTL standards while providing CMOS output characteristics. The device is housed in a 20-pin SOIC package designed for surface-mount installation. It functions as a high-speed Schottky logic component suitable for bus-oriented memory and address drivers.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides eight non-inverting buffer channels with independent three-state control
• Features Schottky-clamped inputs to prevent false triggering during slow signal transitions
• Designed for direct interface between TTL logic sources and CMOS loads

Buffers, Drivers, Receivers, Transceivers Applications

• Bus-oriented memory address drivers
• Clock buffer circuits
• TTL-to-CMOS level translation interfaces

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and RoHS status. Ensure the SOIC-20 package variant matches your PCB footprint requirements. Confirm that the operating temperature range aligns with your system's thermal design specifications before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed switching performance is required alongside robust noise immunity provided by Schottky clamping. It is appropriate for designs needing to drive multiple CMOS loads from a single TTL source. Consider the power dissipation capabilities of the SOIC package relative to your board's thermal management strategy.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74S series of high-speed Schottky logic devices. It shares functional similarities with other octal buffers like the SN74LS244 but offers faster propagation delays. The DWG4 designation indicates a specific tape-and-reel or tube packaging option depending on distribution channels.
