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

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.
