74VHC14FT

TOSHIBA · Inverters · TSSOP-14

74VHC14FT from TOSHIBA, in a TSSOP-14. 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 1A input Schmitt-trigger input of inverter 1. Input voltage range 0 to 5.5 V (independent of Vcc). Typical Vp = 3.15 V, Vn = 1.35 V, VH = 0.4 V at Vcc = 4.5 V.
2 1Y output Inverted CMOS output of Schmitt inverter 1. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
3 2A input Schmitt-trigger input of inverter 2. Input voltage range 0 to 5.5 V.
4 2Y output Inverted CMOS output of Schmitt inverter 2. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
5 3A input Schmitt-trigger input of inverter 3. Input voltage range 0 to 5.5 V.
6 3Y output Inverted CMOS output of Schmitt inverter 3. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
7 GND power_in Ground reference (0 V). Connect to system ground.
8 4Y output Inverted CMOS output of Schmitt inverter 4. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
9 4A input Schmitt-trigger input of inverter 4. Input voltage range 0 to 5.5 V.
10 5Y output Inverted CMOS output of Schmitt inverter 5. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
11 5A input Schmitt-trigger input of inverter 5. Input voltage range 0 to 5.5 V.
12 6Y output Inverted CMOS output of Schmitt inverter 6. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
13 6A input Schmitt-trigger input of inverter 6. Input voltage range 0 to 5.5 V.
14 VCC power_in Positive supply voltage. Operating range 2.0 to 5.5 V (absolute max 7.0 V). Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.
