CD4093BE consists of four Schmitt trigger circuits. Each circuit functions as a two input NAND gate with Schmitt trigger action on both inputs. The gate switches at different points for positive- and negative-going signals. The difference between the positive voltage (VP) and the negative voltage (VN) is defined as hysteresis voltage (VH).
Schmitt trigger action on each input with no external components
Hysteresis voltage typically 0.9 V at VDD = 5V and 2.3V at VDD = 10V
Noise immunity greater than 50%
No limit on input rise and fall times
Standardised, symmetrical output characteristics
100% tested for quiescent current at 20V
Maximum input current of 1µA at 18V over full package temperature range, 100nA at 18V and 25°C
