74HC9114

The 74HC9114 is designed as high-speed si-gate CMOS devices and are pin compatible with low power schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. It is nine wide schmitt trigger inverting buffer with open drain outputs and Schmitt trigger inputs. The Schmitt trigger action in the data inputs transform slowly changing input signals into sharply defined jitter-free output signals. It has 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 to establish a logic HIGH level.

It has three features. The first one is schmitt trigger action on all data inputs. The second one is its output capability is standard (open drain). The third one is its ICC category is MSI. That are all the main features.

Some important AC characteristics and transfer characteristics have been concluded into several points as follow.For Tamb=25°C the first one is about its propagation delay An to Yn which would be typ 36ns and max 110ns at Vcc=2.0V and would be typ 13ns and max 22ns at Vcc=4.5V and would be typ 10ns and max 19ns at Vcc=6.0V. The second one is about its output transition time which would be typ 19ns and max 75ns at Vcc=2.0V and typ 7ns and max 15ns at Vcc=4.5V and would be typ 6ns and max 13ns at Vcc=6.0V. The third one is about its positive going threshold which would be min 0.70V and typ 1.13V and max 1.50V at Vcc=2.0V and min 1.75V and typ 2.37V and max 3.15V at Vcc=4.5V and min 2.30V and typ 3.11V and max 4.20V at Vcc=6.0V. The fourth one is about its negative going threshold which would be min 0.30V and typ 0.70V and max 1.10V at Vcc=2.0V and min 1.35V and typ 1.80V and max 2.40V at Vcc=4.5V and min 1.80V and typ 2.43V and max 3.30V at Vcc=6.0V.
