Notice documents
ON Semiconductor
End-of-life notification for the onsemi NC7SZ125 TinyLogic UHS buffer family. onsemi's official datasheet Rev. 4 (Page 5) marks this family 'DISCONTINUED: These devices are not available.' Last-time-buy inventory available via authorized distributors and Rochester Electronics. Direct P2P drop-in replacement: SN74LVC1G125DBVR (Texas Instruments, SOT-23-5).
NC7SZ125 cross reference and pin-to-pin alternatives
Review mapped pin-to-pin alternatives for NC7SZ125 from ON Semiconductor. Compare package, lifecycle, stock, and sourcing context before moving to RFQ or engineering approval.
Pin-to-pin P2P drop-in for the obsolete onsemi NC7SZ125. Same SOT-23-5 footprint, same pinout (1=OE, 2=A, 3=GND, 4=Y, 5=VCC), same 3-state buffer function, similar propagation delay (~2.5 ns at 3.3 V vs ~2.0 ns for NC7SZ125). The SN74LVC1G125 family from TI is the industry-standard cross-vendor alternative and the recommended direct replacement per Z2Data and Ovaga part cross-reference. Operating voltage range is identical (1.65 V to 5.5 V). onsemi has marked NC7SZ125 as 'DISCONTINUED' in the official datasheet (Rev. 4, Page 5).

Pin-to-pin P2P drop-in for the obsolete onsemi NC7SZ125 from Nexperia. 74LVC1G125GV is the Nexperia / NXP equivalent in SOT-23-5 with identical pinout (1=OE, 2=A, 3=GND, 4=Y, 5=VCC), 1.65 V to 5.5 V VCC range, and the same CMOS 3-state buffer topology. Industry-standard cross-vendor drop-in for the TinyLogic NC7SZ family. Same 3-state output enable behavior, same quiescent current class.

Pin-to-pin P2P drop-in for the obsolete onsemi NC7SZ125 from TI. SN74AUP1G125DBVR is the TI AUP-family single bus buffer gate in SOT-23-5 with identical pinout (1=OE, 2=A, 3=GND, 4=Y, 5=VCC). Listed in TI's Little Logic Guide as the cross-reference for the NC7SZ family. Lower-power variant of LVC with 0.8 V to 3.6 V VCC range; compatible at the 1.8 V to 3.3 V operating range where NC7SZ is typically deployed. Recommended when the application is in the 1.8 V core logic domain.

Functional alternative to the obsolete onsemi NC7SZ125. SN74AHC1G125DBVR is the TI AHC (Advanced High-Speed CMOS) single bus buffer gate in SOT-23-5 with the same pinout and 3-state output enable as NC7SZ125. AHC family operates at 2 V to 5.5 V VCC and provides higher output drive (±8 mA) than UHS NC7SZ. Same 3-state buffer function but functionally equivalent for applications where the higher drive is acceptable. Use as drop-in when design needs more output drive than the low-power NC7SZ can deliver.
