Radiation Hardened Hex Inverting Schmitt Trigger

The Radiation Hardened ACS14MS is a Hex Inverting Schmitt Trigger. This device simply inverts the level present on each input. 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.
