Description
The SN74LVC126ABQAR is TI’s quad buffer/driver with 3-state outputs (LVC family). It provides four noninverting buffers (D1→Q1, D2→Q2, D3→Q3, D4→Q4) whose outputs can be individually tri-stated via separate enable inputs, making it useful for buffering and bus sharing or level shifting between devices.
Key features:
- Supply voltage: 1.65 V to 3.6 V (low-voltage CMOS)
- Four independent buffers with 3-state outputs (enables are active to drive or tri-state)
- CMOS-compatible input thresholds and rail-to-rail outputs
- Fast CMOS performance with low static power and ESD protection
- Pb-free, RoHS-compliant, available in tape-and-reel packaging (suffix -AR)
Typical uses:
- Microcontroller or microprocessor I/O expansion
- Buffering signals between devices on mixed-voltage buses
- Level shifting and isolation in digital interfaces
Note: Always check the latest TI datasheet for exact electrical specs and packaging details.

Pinout
Pin count: 8 pins (in an 8-pin VSSOP/SOIC package, ABQAR).
Function: Dual 3-state (tri-state) noninverting buffer/line driver. Two independent channels: A1→Y1 and A2→Y2, each with its own output-enable input. When enabled, Y follows A; when disabled, Y is high-impedance.
