Radiation Hardened Quad 2-Input NAND Schmitt Trigger



The Radiation Hardened ACS132MS is a Quad 3-Input NAND Gate with Schmitt Trigger inputs. When any input to one of the gates is at a LOW level, the corresponding Y output will be HIGH. A HIGH level on both inputs will cause the output for that gate to be LOW. The Schmitt Trigger input stage provides 400mV (Min) of hysteresis and permits input signals with longer rise times. All inputs are buffered and the outputs are designed for balanced propagation delay and transition times.
