| 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- 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- 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 OE DIR 19 1 G3 3 EN 1 [BA] 3 EN 2 [AB] 1 2 A2 A3 A4 A5 A6 A7 A8 3 4 5 6 7 8 9 17 16 15 14 13 12 11 B2 B3 B4 B5 B6 B7 B8 18 B1 DIR A1 A2 A3 A4 A5 A6 A7 A8 1 2 3 4 5 6 7 8 9 20 VCC 19 18 17 16 15 14 13 12 11 OE B1 B2 B3 B4 B5 B6 B7 B8 A1 2 GND 10 Truth Table Inputs Outputs DIR L H X A=B B=A Z Function A-Bus Output Input Z B-Bus Input Output OE L L H X: Don't care Z: High impedance 2 2007-10-19 TC7MAR2245FK Absolute Maximum Ratings (Note 1) Characteristics Power supply voltage DC input voltage (DIR, OE ) DC bus I/O voltage Input diode current Output diode current DC output current Power dissipation DC VCC/ground current Storage temperature Symbol VCC VIN VI/O IIK IOK IOUT PD ICC/IGND Tstg Rating -0.5~4.6 -0.5~4.6 -0.5~4.6 (Note 2) -0.5~VCC + 0.5 (Note 3) -50 50 50 Unit V V V mA (Note 4) mA mA mW mA C 180 100 -65~150 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). Note 2: Off-state Note 3: High or low state. IOUT absolute maximum rating must be observed.

Unused inputs and bus inputs must be tied to either VCC or GND. Please connect both bus inputs and the bus outputs with VCC or GND when the I/O of the bus terminal changes by the function. In this case, please note that the output is not short-circuited.
