The SN7427N10 is a triple 3-input NOR gate. It outputs low when any input is high, high only when all three are low.
The Bulk package ships loose in an anti-static bag or tube.
The SN7427N10 is a standard 14-pin DIP. Pin 1 is identified by a notch and a dot. The pinout follows the conventional 74-series triple 3-input NOR gate layout: ground on pin 7, VCC on pin 14, with the three gates occupying pins 1-6 and 8-13. Refer to the datasheet for the exact pin mapping.
The SN7427N and SN7427N10 are functionally identical triple 3-input NOR gates. The suffix difference typically indicates a packaging or shipping variation — the SN7427N10 is specifically listed in Bulk package. Electrically they are the same part.
