MC74VHC1G125P5T5G-L22088

Overview

The MC74VHC1G125P5T5G is a single non-inverting 3-state buffer from the VHC logic series, manufactured by onsemi. It operates within a supply voltage range of 2.0 V to 5.5 V and features CMOS-level input thresholds. The device provides high noise immunity through a buffered three-stage internal circuit. It supports partial power down protection via IOFF functionality and includes over-voltage tolerant inputs and outputs up to 5.5 V. The component is housed in a SOT-953 package with five pins.

Feature Summary

• Single non-inverting buffer with 3-state output capability for bus-oriented applications
• Over-voltage tolerant inputs and outputs allow safe interfacing between 5 V and 3 V circuits
• IOFF feature enables partial power down protection to minimize leakage current
• CMOS-level input thresholds ensure compatibility with standard digital logic families

Applications

• Bus-oriented systems requiring signal buffering and isolation
• Clock distribution networks utilizing 3-state control
• Memory module data line drivers
• Interface circuits between different voltage domains

Procurement Notes

Verify the specific ordering suffix P5T5G corresponds to the SOT-953 package and tape-and-reel shipping configuration. Confirm that the -Q suffix is absent, as this indicates standard commercial grade rather than automotive qualification. Ensure the datasheet revision matches the required manufacturing date code for production integration.

Selection Notes

Select this component when a single-channel non-inverting buffer with tri-state control is required in a compact surface-mount footprint. The VHC series offers faster propagation delays compared to older HC/HCT families while maintaining low power consumption. Verify that the 8 mA source/sink drive capability meets the load requirements of the destination circuitry.

Part Context

This part belongs to the MC74VHC1G125 family of single buffers. It shares functional similarities with the MC74VHC1G126 (active-low enable) and MC74VHC1G125DFT2G (SC-88A package). The P5 suffix specifically denotes the SOT-953 package variant, distinguishing it from SC-88A or UDFN6 options available in the same logical family.

Replacement Considerations

MC74VHC1G125DFT2G: Equivalent function in SC-88A package. MC74VHC1G126P5T5G: Similar buffer but with active-low OE pin. MC74VHC1G125DBVT1G: Equivalent function in SC-74A package.
