Overview: TC74VHC9541P/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC74VHC9541P, TC74VHC9541FK Octal Universal Schmitt Buffer with 3-State Outputs
The TC74VHC9541 is an ultra-high-speed octal Schmitt buffer fabricated using silicon-gate CMOS technology. The TC74VHC9541 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 TC74VHC9541 as an inverter; a logic HIGH on the CONT input configures the TC74VHC9541 as a buffer.
All the inputs have hysteresis between the positive-going and negativegoing thresholds. Thus the TC74VHC9541 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 VCC. This 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 TC74VHC9541 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.
