Nexperia · Buffers, Drivers, Receivers, Transceivers · TSSOP-14

74LVT126PW from Nexperia, in a TSSOP-14. 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 1OE input Output enable input for buffer 1; a LOW on nOE puts outputs 1Y into the high-impedance OFF-state.
2 1A input Data input for buffer 1, overvoltage tolerant to 5.5 V with bus-hold, operating from 0 V to 5.5 V.
3 1Y output 3-state data output of buffer 1, which goes high impedance when 1OE is LOW.
4 2OE input Output enable input for buffer 2; a LOW on nOE puts outputs 2Y into the high-impedance OFF-state.
5 2A input Data input for buffer 2, overvoltage tolerant to 5.5 V with bus-hold, operating from 0 V to 5.5 V.
6 2Y output 3-state data output of buffer 2, which goes high impedance when 2OE is LOW.
7 GND power_in Ground (0 V) reference for all voltages on the device.
8 3Y output 3-state data output of buffer 3, which goes high impedance when 3OE is LOW.
9 3A input Data input for buffer 3, overvoltage tolerant to 5.5 V with bus-hold, operating from 0 V to 5.5 V.
10 3OE input Output enable input for buffer 3; a LOW on nOE puts outputs 3Y into the high-impedance OFF-state.
11 4Y output 3-state data output of buffer 4, which goes high impedance when 4OE is LOW.
12 4A input Data input for buffer 4, overvoltage tolerant to 5.5 V with bus-hold, operating from 0 V to 5.5 V.
13 4OE input Output enable input for buffer 4; a LOW on nOE puts outputs 4Y into the high-impedance OFF-state.
14 VCC power_in Supply voltage, specified from 2.7 V to 3.6 V.
