Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix QG corresponds to the 20-pin QSOP package configuration. Confirm current manufacturing status as this part number may be subject to end-of-life notices or obsolescence. Ensure compatibility with existing board layouts designed for standard '244 pinouts before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a low-voltage octal bus switch is required that maintains compatibility with legacy '244 logic pinouts. It is suitable for designs needing bidirectional data transfer with high isolation capabilities. Consider the 20-pin QSOP package constraints and the 2.3V to 3.6V supply voltage requirements during circuit design.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the 74CBTLV series of low-voltage bus switches. It serves as a bridge for connecting different data buses while maintaining signal integrity at lower voltage levels. The device is part of Renesas Electronics' portfolio following their acquisition of IDT, continuing the lineage of high-performance CMOS logic solutions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Public confirmed substitute part numbers include 74CBTLV3244PGG and 74CBTLV3244PGG8. These alternatives offer similar functionality but differ in package type (TSSOP vs QSOP). Verify pin compatibility and thermal characteristics when substituting.
