TOSHIBA LJ CT · Buffer/Driver/Transceiver · SOT-23-5
TC7SZ125F from TOSHIBA LJ CT, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ~G | input | Active-low output enable. When ~G is High the Y output is placed in the High-Impedance (Z) state; when ~G is Low the buffer drives Y with the logic level of input A. 5.5 V tolerant input. |
| 2 | A | input | Buffer data input. Its logic level (H/L) is passed to output Y when ~G is Low; input is 'don't care' when ~G is High. CMOS-level input, 5.5 V tolerant. |
| 3 | GND | power_in | Ground reference (0 V) for the device. |
| 4 | Y | tri_state | 3-state buffer output. Drives the logic level of input A when ~G is Low; enters High-Impedance state when ~G is High. Guaranteed drive ±24 mA min at VCC = 3.0 V; output is 5.5 V power-down protected. |
| 5 | VCC | power_in | Positive supply input. Operating range 1.65 V to 5.5 V (data retention down to 1.5 V). Absolute maximum 6.0 V. Decouple with a 0.1 µF ceramic capacitor to GND close to the pin. |
