74LVC1G125SE-7

74LVC1G125SE-7 is a single-channel, non-inverting buffer with a tri-state output in the 74LVC1G125 family. It buffers a logic input to the output when its enable input (OE) is in the active state; otherwise the output is high-impedance, allowing multiple devices to share a bus. It operates from a supply voltage of 1.65 to 5.5 V (CMOS thresholds) and is suitable for level shifting and buffering between devices with different Vcc within that range. It is a low-power, high-speed CMOS device with standard ESD protection and moderate output drive for typical loads. The SE-7 suffix indicates a specific small-package variant and RoHS-compliant lead finish; exact package type (such as SC-70/SOT-23-5) and temperature range are vendor-specific—consult the datasheet. Applications include buffering microcontroller I/O, bus interfacing, signal isolation, and simple level translation in mixed-voltage systems. Note: enable logic is typically described in the datasheet (active-high vs active-low).

74LVC1G125SE-7 is a single noninverting buffer with a 3-state output (OE\). Typical applications include:
- Level shifting/bridging between voltage domains (1.65–3.6 V devices).
- Buffering and driving signals to reduce source loading and increase fan-out.
- Tri-state bus buffering for shared data/address lines or I/O expansion (OE\ controls isolation).
- Interface between microcontrollers/FPGA and peripherals (RAM, LCDs, sensors) requiring selective enable.
- Power-down isolation to prevent back-powering or leakage when devices are off.

The 74LVC1G125SE-7 is in a SC‑70 (SC‑70‑6) 6‑pin small‑outline package (a tiny SMD package).
