Quadruple 2-input NOR gate
DESCRIPTION
The HEF4001UB is a quadruple 2-input NOR gate. This
unbuffered single stage version provides a direct
implementation of the NOR function. The output
impedance and output transition time depends on the input
voltage and input rise and fall times applied.

APPLICATION INFORMATION
Some examples of applications for the HEF4001UB are shown below. Because of the fact that this circuit is unbuffered,
it is suitable for use in (partly) analogue circuits.

In Fig.9 the oscillation frequency is mainly determined by R1C1, provided
R1 << R2 and R2C2 << R1C1.
The function of R2 is to minimize the influence of the forward voltage
across the protection diodes on the frequency; C2 is a stray (parasitic)
capacitance. The period Tp is given by Tp = T1 + T2, in which
V DD + V ST
2V DD – V ST
T 1 = R1C1 ln --------------------------- and T 2 = R1C1 ln --------------------------------- where

VST is the signal threshold level of the gate. The period is fairly
independent of VDD, VST and temperature. The duty factor, however, is
influenced by VST.

NOTES
If a gate is just used as an amplifying inverter, there are
two possibilities:
1. Connecting the inputs together gives simpler wiring,
but makes the device output not completely
symmetrical.
2. Connecting one input to VSS will give the device a
symmetrical output.
