TC7MP85410FT
Octal Bus Buffer with Output Series Resistor
The TC7MP85410 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 to the
TC7MP85410 can be used as a level converter for interfacing
3.3-V systems to 5-V systems.
The TC7MP85410 is a non-inverting bus buffer.
The outputs have 47-Ω (typ.) resistors connected in series, which
can reduce reflection noise without using external resistors.
Weight: 0.08 g (typ.)
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 TC7MP85410 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.
•

•
TTL-level inputs: VIL = 0.8 V (max)
VIH = 2.0 V (max)
•
Power-down protection is provided on all inputs.
•
Low noise: VOLP = 0.35 V (typ)

Note 1: Exceeding any of the absolute maximum ratings, even briefly, may lead to deterioration in IC performance
or even destruction.
Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly
even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute
maximum ratings and the operating ranges.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
