74LVC1G125W5-7

74LVC1G125W5-7 is a single-channel, non-inverting buffer with a tri-state (3-state) output from the 74LVC1G125 family. It buffers a logic signal and can drive or gate it onto a bus when enabled; the output can be placed in high impedance when disabled via the OE input.
Key points:
- Voltage range: Vcc typically 1.65–3.6 V (works with 1.8/3.3 V systems).
- Logic: CMOS, low static/dynamic power; fast switching.
- Features: Ioff support for partial-power-down; standard input thresholds compatible with CMOS/TTL logic.
- Packaging: W5-7 is a small-footprint, RoHS-compliant package option.
Typical uses:
- Buffering signals between digital blocks.
- Level shifting or interfacing between domains.
- Gate buffering for a shared bus or line.
Truth (conceptual): When OE is asserted/enabled, input A is passed to output Y; when OE is deasserted, Y is high-impedance.

Key features of 74LVC1G125W5-7:
- 1-bit buffer/driver with 3-state (tri-state) output
- Output enable (OE) input; OE is active HIGH
- Vcc range: 1.65 V to 5.5 V (LVC family)
- TTL/CMOS input compatible
- Output goes high-impedance when OE = 0
- Very small 5-pin W5-7 package (SC‑70/5 type); low power consumption
Optional: suitable for simple buffering, level shifting, and I/O isolation in mixed-logic systems.

Pin count: 5 pins (SC-70/SOT-23-5 package).
Function: Single non-inverting buffer with a tri-state output. Inputs: A (data), G (output enable, active HIGH). Output: Y. Includes Vcc and GND. When G is HIGH, Y = A; when G is LOW, Y is high-impedance.

- Manufacturer: Nexperia.
- What kind of company: A global semiconductor company specializing in standard logic ICs, discretes, MOSFETs, and ESD/protection devices for automotive, industrial, and consumer electronics.

74LVC1G125W5-7 is a 1-bit, noninverting buffer with a tri-state output (OE). Common applications:
- Data/bus buffering and isolation between devices (MCUs, memories, FPGAs)
- Tri-state bus driver for shared lines to prevent contention
- Level shifting/interface between different voltage domains
- Gate/enable-controlled data paths for clocks or control signals
- Compact, low-pin-count buffering in space-constrained designs
These uses leverage its simple buffering plus controllable output enable.
