Functional DescriptionFunctional Description Octal Universal Schmitt Buffer with 3-State Outputs 2. 2. 2. 2. GeneralGeneralGeneralGeneral The 74VHCT9541AFT is an ultra-high-speed octal Schmitt buffer fabricated using silicon-gate CMOS technology. The 74VHCT9541AFT combines low power consumption of CMOS with Schottky TTL speeds. The input voltage are compatible with TTL output voltage. This device may be used as a level converter for interfacing 3.3 V to 5 V system. 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 74VHCT9541AFT as an inverter a logic HIGH on the CONT input configures the 74VHCT9541AFT as a buffer. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHCT9541AFT is capable of squaring up transitions of slowly changing input signals and provides an improved noise immunity. Input protection and output circuit ensure that 0 to 5.5 V can be applied to the input and output (Note) pins without regard to the supply voltage. These structure prevents device destruction due to mismatched supply and input/output voltages such as battery back up, etc. Note: Output in off-state 3. 3. FeaturesFeatures 3. 3.
