# TC7SH126FU

**TOSHIBA** · Buffers / Drivers · SOT-353

TC7SH126FU from TOSHIBA, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Output enable input; when G is low OUT Y is high impedance, and when G is high OUT Y follows IN A, with inputs tolerant up to 5.5 V. |
| 2 | IN A | input | Buffer data input, 5.5 V tolerant (VIN 0 to 5.5 V), and unused inputs must be tied to VCC or GND. |
| 3 | GND | power_in | Ground pin (0 V reference) for the device. |
| 4 | OUT Y | tri_state | 3-state buffer output that is high impedance when G is low, with IOH/IOL of -8 mA/8 mA at VCC = 4.5 V and output voltage range 0 to VCC. |
| 5 | VCC | power_in | Supply voltage pin with operating range 2.0 to 5.5 V (absolute maximum -0.5 to 7.0 V). |

## CAD (KiCad official)

- Symbol: `TC7SH126FU`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SOT-353 (KiCad packages3D, STEP)
- 3D model files: `tc7sh126fu-etched.step` / `tc7sh126fu-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tc7sh126fu.step` / `tc7sh126fu.glb` are the bare package body.
