4077B

      The 4077B is designed to contain four independent exclusive-NOR gates integrated on a single monolithic silicon chip.And also each exclusive-NOR gate consists of five N-channel and five P-channel enhancement mode transistors,plus output buffering devices.
      4077B has three features.The first one is that it would have the buffered outputs.The second one is that it is designed to have the diode protection on all inputs.The third one is that 4077B would be fully "B"-series compatible.That are all the features.
      Some recommended operating conditions of 4077B have been concluded into several points.For maximum reliability,The DC supply voltage which also marked as Vdd or Vss would be from 3 to 15 Vdc.Then the operating temperature,which also be marked as Ta,would be from -55 to +125°C for C and would be from -40 to 85°C for E.Also some electrical characteristics about it which is about its quiescent device current which also be marked as Idd.When Vdd(Vdc) = 5 4077B would have a maximum of 0.05 uAdc at T(low) and have a typical of 0.0005 uAdc and a maximum of 0.05 uAdc at the room tempreture of +25°C and  have a maximum of 1.5 uAdc at T(high). When Vdd(Vdc) = 10 it would have a maximum of 0.10 uAdc at T(low) and have a typical of 0.001 uAdc and a maximum of 0.10 uAdc at the room tempreture of +25°C and  have a maximum of 3.0 uAdc at T(high). When Vdd(Vdc) = 15 4077B would have a maximum of 0.20 uAdc at T(low) and have a typical of 0.002 uAdc and a maximum of 0.20 uAdc at the room tempreture of +25°C and  have a maximum of 6.0 uAdc at T(high).
      Some notes baout 4077B electrical characteristics is that the T(low) would be -55°C for C and would be -40°C for E.Also the T(high) would be +125°C for C and would be +85°C for E.
