TC7MA245FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA245FK Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs The TC7MA245FK 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. All inputs are equipped with protection circuits against static discharge. Weight: 0.03 g (typ.) Features • Low voltage operation: VCC = 1.8~3.6 V • High speed operation: tpd = 3.5 ns (max) (VCC = 3.0~3.6 V) tpd = 4.2 ns (max) (VCC = 2.3~2.7 V) tpd = 8.4 ns (max) (VCC = 1.8 V) • 3.6 V tolerant inputs and outputs. • Package: VSSOP (US20) • Output current: IOH/IOL = ±24 mA (min) (VCC = 3.0 V) IOH/IOL = ±18 mA (min) (VCC = 2.3 V) IOH/IOL = ±6 mA (min) (VCC = 1.8 V) • Latch-up performance: ±300 mA • ESD performance: • Human body model > ±2000 V Machine model > ±200 V • 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 2001-10-23 TC7MA245FK 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 B2 A4 5 16 B3 A5 6 15 B4 A3 A6 7 14 B5 A4 A7 8 13 B6 A8 9 12 B7 A5 A6 11 2 G3 3 EN 1 [BA] 3 EN 2 [AB] 18 1 B1 2 A2 GND 10 19 1 B8 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 A-Bus B-Bus L L A=B Output Input L H B=A Input Output H X Z Z X: Don’t care Z: High impedance 2 2001-10-23 TC7MA245FK Maximum Ratings 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 −50 Output diode current IOK ±50 DC output current IOUT ±50 mA Power dissipation PD 180 mW ICC/IGND ±100 mA Tstg −65~150 °C DC VCC/ground current Storage temperature −0.5~4.6 (Note1) −0.5~VCC + 0.5 (Note2) V mA (Note3) mA Note1: Off-state Note2: High or low state.
