A single stage inverting function with standard output performance is also accomplished. The outputs are fully buffered for highest noise immunity and pattern insensitivity of output impedance.

Fig.4 Fig.5 Voltage gain (VO/VI) as a function of supply voltage. Supply current as a function of supply voltage. This is also an example of an analogue amplifier using the single inverter stage (I7/O3) of the HEF4000B. Fig.6 Test set-up for measuring graphs of Figs 4 and 5.
