Philips 74HC9115
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. The 74HC/HCT9115 are nine wide Schmitt trigger buffer with open drain outputs and Schmitt trigger inputs.FEATURES
● Schmitt trigger action on all data inputs● Output capability: standard (open drain)
● ICC category: MSI
GENERAL DESCRIPTION
7A. 74HC/HCT9115 The Schmitt trigger action in the data inputs transform slowly changing input signals into sharply defined jitter-free output signals. 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. The “9115” is identical to the “9114” but has non-inverting outputs.
