TC7MP85400FT

Octal Bus Buffer with Output Series Resistor

The TC7MP85400 is an advanced high-speed CMOS octal bus

buffer fabricated with silicon-gate CMOS technology. It achieves

high-speed operation similar to the equivalent bipolar Schottky

TTL while maintaining the CMOS low power dissipation. The

inputs are compatible with TTL voltage levels, so

the

TC7MP85400 can be used as a level converter for interfacing

3.3-V systems to 5-V systems.

The TC7MP85400 is an inverting bus buffer.

The outputs have 47-

Ω (typ.) resistors connected in series, which

can reduce reflection noise without using external resistors.

Input and output protection circuits ensure that 0 to 5.5V can be

applied to the input and output*1 pins without regard to the

supply voltage.

Since power-down protection is provided on both inputs and outputs, the TC7MP85400 can be used in a wide range

of applications, such as interfacing between two different voltage systems, backup battery systems and so on.

Features

• Outputs have 47-Ω (typ.) resistors connected in series.

• Power-down protection is provided on all inputs.
