FEATURES • Schmitt trigger action on all data inputs • Output capability: standard (open drain) The 74HC/HCT9115 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 HIGH, 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 to establish a logic HIGH level. • ICC category: MSI GENERAL DESCRIPTION The 74HC/HCT9115 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 “9115” is identical to the “9114” but has non-inverting outputs. The 74HC/HCT9115 are nine wide Schmitt trigger buffer with open drain outputs and Schmitt trigger inputs.

CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz fo = output frequency in MHz ∑ (CL × VCC2 × fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2.
