TC74VHC9125,9126P/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC9125P, TC74VHC9125FK TC74VHC9126P, TC74VHC9126FK TC74VHC9125P/FK 5-bit Universal Schmitt Buffer with 3-State Outputs TC74VHC9126P/FK 5-bit Universal Schmitt Buffer with 3-State Outputs The TC74VHC9125/9126 are an ultra-high-speed 5-bit Schmitt buffer fabricated using silicon-gate CMOS technology. The TC74VHC9125/9126 combines low power consumption of CMOS with Schottky TTL speeds. Y1 to Y4 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 TC74VHC9125/9126 as an inverter; a logic HIGH on the CONT input configures the TC74VHC9125/9126 as a buffer. TC74VHC9125 Y5 output is an inverting type, and the TC74VHC9126 Y5 output is a non-inverting type. All the inputs have hysteresis between the positive-going and negativegoing thresholds. Thus the TC74VHC9125/9126 are 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 TC74VHC9125/9126 ideal for a wide range of applications, such as interfacing between different voltages, voltage translation from 5 V to ...
