TC7MP85410FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic 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. • High speed: tpd = 4.5 ns (typ.) at VCC = 5 V • 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) 1 2007-10-19 TC7MP85410FT Pin Assignment TC7MP85410FT N.C 1 20 VCC A1 2 19 N.C A2 3 18 Y1 A3 4 17 Y2 A4 5 16 Y3 A5 6 15 Y4 A6 7 14 Y5 A7 8 13 Y6 A8 9 12 Y7 GND 10 11 Y8 (top view) Truth Table Inputs Outputs An Yn L L H H Circuit Schematic (1/8 Package) Rout A1 - A8 Y1 - Y8 2 2007-10-19 TC7MP85410FT Absolute Maximum Ratings (Note 1) Characteristics Symbol Rating Unit Supply voltage range VCC −0.5 to 7.0 V DC input voltage VIN −0.5 to 7.0 V −0.5 to 7.0 (Note 2) −0.5 to VCC + 0.5 (Note 3) DC output voltage VOUT Input diode current IIK −20 Output diode current IOK ±20 DC output current IOUT ±25 mA DC VCC/ground current ICC ±75 mA Power dissipation PD 180 mW Storage temperature Tstg −65 to 150 °C V mA (Note 4) mA 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).
