TC74VHC9541P/FT/FK

TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic

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

TC74VHC9541P

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 ( ) 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

negative-going thresholds. Thus the TC74VHC9541 is capable of

squaring up transitions of slowly changing input signals and

provides an improved noise immunity.

TC74VHC9541FT

Additionally, all the inputs have a newly developed protection

circuit without a diode returned to V . 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.
