Philips Semiconductors Product specification Nine wide Schmitt trigger buffer; open drain outputs; inverting 74HC/HCT9114 The Schmitt trigger action in the data inputs transform slowly changing input signals into sharply defined jitter-free output signals. FEATURES • Schmitt trigger action on all data inputs • Output capability: standard (open drain) The 74HC/HCT9114 have open-drain N-transistor outputs, which are not clamped by a diode connected to VCC. In the OFF-state, i.e.
