TC7MAR2245FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MAR2245FK Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs The TC7MAR2245FK is a high performance CMOS octal bus transceiver. Designed for use in 1.8, 2.5 or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. The direction of data transmission is determined by the level of the DIR inputs. The OE inputs can be used to disable the device so that the busses are effectively isolated. The 26-Ω series resistor helps reducing output overshoot and undershoot without external resistor. All inputs are equipped with protection circuits against static discharge. Weight: 0.03 g (typ.) Features • 26-Ω series resistors on outputs. • Low voltage operation: VCC = 1.8~3.6 V • High speed operation: tpd = 4.4 ns (max) (VCC = 3.0~3.6 V) tpd = 5.6 ns (max) (VCC = 2.3~2.7 V) tpd = 9.8 ns (max) (VCC = 1.8 V) • • 3.6 V tolerant inputs and outputs. Output current: IOH/IOL = ±12 mA (min) (VCC = 3.0 V) IOH/IOL = ±8 mA (min) (VCC = 2.3 V) IOH/IOL = ±4 mA (min) (VCC = 1.8 V) • Latch-up performance: −300 mA • ESD performance: Machine model ≥ ±200 V Human body model ≥ ±2000 V • Package: VSSOP (US) • Bidirectional interface between 2.5 V and 3.3 V signals. (*1) • Power down protection is provided on all inputs and outputs. (*2) • Supports live insertion/withdrawal (*3) • Bidirectional interface between 2.5 V and 3.3 V signals. (*1) • Power down protection is provided on all inputs and outputs. (*2) • Supports live insertion/withdrawal (*3) *1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result. *2: All floating (high impedance) bus terminal must have their input level fixed by means of pull up or pull down resistors. *3: To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. 1 2007-10-19 TC7MAR2245FK Pin Assignment (top view) IEC Logic Symbol DIR 1 20 VCC A1 2 19 OE A2 3 18 B1 A3 17 4 OE DIR A1 19 1 2 G3 3 EN 1 [BA] 3 EN 2 [AB] 18 1 B1 2 B2 A2 A4 5 16 B3 A5 6 15 B4 A6 7 14 B5 A4 A7 8 13 B6 A5 A8 9 12 B7 GND 10 11 B8 A3 A6 A7 A8 3 17 4 16 5 15 6 14 7 13 8 12 9 11 B2 B3 B4 B5 B6 B7 B8 Truth Table Inputs Function Outputs OE DIR L L L H A-Bus B-Bus A=B Output Input H B=A Input Output X Z Z X: Don’t care Z: High impedance 2 2007-10-19 TC7MAR2245FK Absolute Maximum Ratings (Note 1) Characteristics Symbol Rating Unit Power supply voltage VCC −0.5~4.6 V DC input voltage (DIR, OE ) VIN −0.5~4.6 V DC bus I/O voltage VI/O Input diode current IIK −0.5~4.6 (Note 2) −0.5~VCC + 0.5 (Note 3) −50 V mA Output diode current IOK ±50 DC output current IOUT ±50 mA Power dissipation DC VCC/ground current (Note 4) mA PD 180 mW ICC/IGND ±100 mA Tstg −65~150 °C Storage temperature Note 1: Exceeding any of the absolute maximum ratings, even briefly, 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).
