SN74HCS266QDRQ1

Texas Instruments · Gates · SOIC-14

SN74HCS266QDRQ1 from Texas Instruments, in a SOIC-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 1A input Channel 1 input A of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
2 1B input Channel 1 input B of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
3 1Y output Channel 1 open-drain output Y (Y = A XNOR B), which can only drive low and needs an external pull-up resistor for a high level.
4 2Y output Channel 2 open-drain output Y (Y = A XNOR B), which can only drive low and needs an external pull-up resistor for a high level.
5 2A input Channel 2 input A of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
6 2B input Channel 2 input B of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
7 GND power_in Ground reference pin for the device.
8 3A input Channel 3 input A of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
9 3B input Channel 3 input B of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
10 3Y output Channel 3 open-drain output Y (Y = A XNOR B), which can only drive low and needs an external pull-up resistor for a high level.
11 4Y output Channel 4 open-drain output Y (Y = A XNOR B), which can only drive low and needs an external pull-up resistor for a high level.
12 4A input Channel 4 input A of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
13 4B input Channel 4 input B of the XNOR gate, a Schmitt-trigger CMOS input that tolerates slow or noisy signals.
14 VCC power_in Positive power supply pin for the device.
