| FFF Compatibility | The pin assignments, names, functions, and footprint are identical to the original part.Both parts are in the standard 20-TSSOP package with identical dimensions.Both parts belong to the 74AHC logic family and share identical electrical specs and supply voltage. | Pinout is logically and physically compatible, but pin designations differ in naming index (0-7 vs 1-8 indexing).Standard 20-TSSOP package matches the footprint and physical size exactly.Electrical performance matches the original part across all parameters. | ||
 AI Summary | SN74AHC541PWG4 by Texas Instruments: Buffer, Non-Inverting 1 Element 8 Bit per Element 3-State Output 20-TSSOP. | This is the direct active replacement from Texas Instruments for the obsolete G4 suffix part. It belongs to the same logic series and has identical electrical and physical characteristics, differing only in the tape-and-reel packaging standard.
| This is an active, highly compatible second-source alternative from Nexperia. It matches the logic family, electrical parameters, and package dimensions, with only minor differences in pin labeling conventions in the documentation.
