Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGVR' to confirm the TVSOP-20 package type and reel packaging configuration. Ensure compatibility with the required 1.65 V to 3.6 V supply voltage range for your target application. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring low-voltage operation between 1.65 V and 3.6 V with high-speed signal integrity. The ±24 mA drive strength makes it suitable for driving moderate capacitive loads on system buses. Consider the TVSOP-20 package dimensions for PCB layout constraints. This device is appropriate for applications needing eight-channel buffering with three-state control, offering a balance of speed and power efficiency compared to standard CMOS alternatives.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the SN74ALVCH244 family of octal buffers and line drivers. It is designed for low-voltage digital logic applications, providing enhanced performance over traditional 5 V devices. The device integrates eight independent non-inverting buffers with three-state outputs, controlled by separate enable inputs. It is widely used in portable electronics and communication equipment where power consumption and signal speed are critical design parameters.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ALVCH244DWRE4 is a documented substitute variant featuring similar electrical characteristics but utilizes a SOIC-20 package instead of TVSOP-20. Verify pinout compatibility and thermal performance differences when substituting packages. Other family members like SN74AHC244 offer higher voltage ranges but may not fit low-voltage designs.
