| TC74VCX245FT/FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VCX245FT, TC74VCX245FK, TC74VCX245FTG Low-Voltage Octal Bus Transceiver with 3.6 V Tolerant Inputs and Outputs The TC74VCX245 is a high performance CMOS octal bus transceiver which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5V, 1.8V, 2.5V 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.

Note 1: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result. Note 2: All floating (high impedance) bus terminal must have their input level fixed by means of pull up or pull down resistors. Note 3: When mounting VQON package, the type of recommended flux is RA or RMA. 1 2007-10-19 TC74VCX245FT/FK/FTG Pin Assignment (top view) FT(TSSOP20-P-0044-0.65) FK(VSSOP20-P-0030-0.50) DIR A1 A2 A3 A4 A5 A6 A7 A8 1 2 3 4 5 6 7 8 9 20 19 18 17 16 15 14 13 12 11 VCC FTG(VQON20-P-0404-0.50) A1 DIR VCC OE 20 19 18 17 B1 16 OE B1 B2 B3 B4 B5 B6 B7 B8 6 A7 7 A2 A3 A4 A5 A6 1 2 3 4 5 15 14 13 12 11 B2 B3 B4 B5 B6 8 9 10 B7 A8 GND B8 GND 10 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 A1 2 Truth Table Inputs Outputs DIR L H X A=B B=A Z Function OE L L H A-Bus Output Input Z B-Bus Input Output X: Don't care Z: High impedance 2 2007-10-19 TC74VCX245FT/FK/FTG 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 -50 50 50 Unit V V (Note 2) V mA (Note 4) mA mA mW mA C -0.5~VCC + 0.5 (Note 3) 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).
