| CD4093BC Quad 2-Input NAND Schmitt Trigger October 1987 Revised January 1999 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 difference 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). Guaranteed s Equal source and sink currents s No limit on input rise and fall time s Standard B-series output drive s Hysteresis voltage (any input) TA = 25C Typical VDD = 5.0V VDD = 10V VDD = 15V VH = 1.5V VH = 2.2V VH = 2.7V VH = 0.1 VDD Features s Wide supply voltage range: s Schmitt-trigger on each input with no external components s Noise immunity greater than 50% 3.0V to 15V Applications * Wave and pulse shapers * High-noise-environment systems * Monostable multivibrators * Astable multivibrators * NAND logic Ordering Code: Order Number CD4093BCM CD4093BCN Package Number M14A N14A Package Description 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-120, 0.150" Narrow Body 14-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" Wide Devices also available in Tape and Reel.
