Philips Semiconductors Product specification Nine wide Schmitt trigger buffer; 74HC/HCT9115 open drain outputs FEATURES The Schmitt trigger action in the data inputs transform slowly changing input signals into sharply defined • Schmitt trigger action on all data inputs jitter-free output signals. • Output capability: standard (open drain) The 74HC/HCT9115 have open-drain N-transistor • I category: MSI CC outputs, which are not clamped by a diode connected to V . In the OFF-state, i.e. when one input is HIGH, the CC GENERAL DESCRIPTION output may be pulled to any voltage between GND and V . This allows the device to be used as a Omax The 74HC/HCT9115 are high-speed Si-gate CMOS LOW-to-HIGH or HIGH-to-LOW level shifter. For digital devices and are pin compatible with low power Schottky operation and OR-tied output applications, these devices TTL (LSTTL). They are specified in compliance with must have a pull-up resistor to establish a logic HIGH level. JEDEC standard no. 7A. The “9115” is identical to the “9114” but has non-inverting The 74HC/HCT9115 are nine wide Schmitt trigger buffer outputs. with open drain outputs and Schmitt trigger inputs.
