FEATURES Schmitt trigger action on all data inputs Output capability: standard (open drain) ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT9114 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT9114 are nine wide Schmitt trigger inverting buffer with open drain outputs and Schmitt trigger inputs.
74HC/HCT9114
The Schmitt trigger action in the data inputs transform slowly changing input signals into sharply defined jitter-free output signals. 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. when one input is LOW, the output may be pulled to any voltage between GND and VOmax. This allows the device to be used as a LOW-to-HIGH or HIGH-to-LOW level shifter. For digital operation and OR-tied output applications, these devices must have a pull-up resistor……
