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 negative-
going 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 3 V and battery back-up circuits.
