CD4093BC
Quad 2-Input NAND Schmitt Trigger
General Description
The CD4093B consists of four Schmitt-trigger circuits. Each circuit functions as a 2-input NAND gate with Schmitttrigger action on both inputs. The gate switches at different points for positive and negative-going signals. The differ-
ence between the positive (VT+) and the negative voltage (VT−) is defined as hysteresis voltage (VH).
All outputs have equal source and sink currents and conform to standard B-series output drive (see Static Electrical Characteristics).
Features
■Wide supply voltage range: 3.0V to 15V
■Schmitt-trigger on each input with no external components
■Noise immunity greater than 50%
■Equal source and sink currents
■No limit on input rise and fall time
■Standard B-series output drive
■Hysteresis voltage (any input) TA = 25°C
