Functional DescriptionFunctional Description Octal Universal Schmitt Buffer with 3-State Outputs 2. 2. 2. 2. GeneralGeneralGeneralGeneral The 74VHC9541FT is an ultra-high-speed octal Schmitt buffer fabricated using silicon-gate CMOS technology. The 74VHC9541FT combines low power consumption of CMOS with Schottky TTL speeds. The outputs can be put in the high-impedance state by placing a logic HIGH on the Enable (G) input. The CONT input determines the logical inversion of data. A logic LOW on the CONT input configures the 74VHC9541FT as an inverter a logic HIGH on the CONT input configures the 74VHC9541FT as a buffer. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHC9541FT is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Additionally, all the inputs have a newly developed protection circuit without a diode returned to V . This CC enables the inputs to be tolerant of up to 5 volts even when power supply is down. The input power-down protection capability makes the 74VHC9541FT ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to 3 V and battery back-up circuits. 3. 3.
