The device provides four independent 2-input OR gates with fully buffered outputs for highest noise immunity and pattern insensitivity to output impedance variations. Operating from 3V to 15V supply, it is specified at 5V, 10V, and 15V parametric ratings. The CMOS architecture provides very low static power dissipation with 1uA maximum quiescent current. Input clamp diodes enable the use of current-limiting resistors to interface inputs to voltages in excess of VDD. All inputs and outputs are protected against electrostatic discharge effects exceeding 2000V HBM. The device complies with JEDEC standard JESD 13-B.","working_principle":"The HEF4071BT implements four independent CMOS OR gate functions. (1) OR Logic: Each gate performs the Boolean OR function Y = A + B, where the output is HIGH when either or both inputs are HIGH. (2) CMOS Implementation: Each OR gate uses complementary N-channel and P-channel MOSFETs in a standard CMOS configuration. The P-channel transistors pull the output HIGH, and the N-channel transistors pull it LOW. (3) Buffered Output: Each gate output includes a buffer stage that isolates the logic decision from the output load, providing symmetrical output impedance and improving noise immunity. (4) Input Protection: Clamp diodes on each input limit the input voltage to one diode drop above VDD or below VSS, protecting the thin gate oxide from electrostatic discharge and over-voltage conditions. (5) Low Static Power: In steady state, no DC path exists between VDD and VSS, resulting in quiescent current below 1uA.","pin_description":"
