74VHC9125FT,74VHC9126FT CMOS Digital Integrated Circuits Silicon Monolithic 74VHC9125FT,74VHC9126FT 1. Functional Description 5-Bit Universal Schmitt Buffer with 3-State Outputs 2. General The 74VHC9125FT/74VHC9126FT are an ultra-high-speed 5-bit Schmitt buffer fabricated using silicon-gate CMOS technology. The 74VHC9125FT/74VHC9126FT 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 74VHC9125FT/74VHC9126FT as an inverter a logic HIGH on the CONT input configures the 74VHC9125FT/74VHC9126FT as a buffer. 74VHC9125FT Y5 output is an inverting type, and the 74VHC9126FT Y5 output is a non-inverting type. All the inputs have hysteresis between the positive-going and negative-going thresholds. Thus the 74VHC9125FT/74VHC9126FT 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 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 74VHC9125FT/74VHC9126FT 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.
