| TC7MP245FK/FTG TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MP245FK, TC7MP245FTG Low-Voltage/Low-Power Octal Bus Transceiver with Bus-hold The TC7MP245 is a high-performance CMOS octal bus transceiver. By a low power consumption circuit, power consumption has been reduced when a bus terminal is disable state (OE=High). The direction of data transmission is determined by the level of the DIR input. The OE input can be used to disable the device so that the busses are effectively isolated. But, bus of a B bus side at floating state is maintained in an appropriate logic level due to a bus hold circuit to a B bus. Moreover, the bus-hold circuit which is added to a B bus is off when OE is low. All inputs are equipped with protection circuits against static discharge. TC7MP245FK TC7MP245FTG VQON20-P-0404-0.50 Features * * Low-voltage operation : VCC = 1.65 to 3.6 V Weight: VSSOP20-P-0030-0.50 : 0.03 g (typ.) VQON20-P-0404-0.50 : 0.0145 g (typ.) Low power current consumption : By a new input circuit, power consumption in OE=H is reduced largely. It is most suitable for battery drive products such as personal digital assistant or a cellular phone. * * Quiescent supply current High-speed operation : ICC = 5A(max)(Vcc=3.6V) : tpd=3.0ns(max)(Vcc=3.30.3V) tpd=4.6ns(max)(Vcc=2.50.2V) tpd=10.0ns(max)(Vcc=1.80.15V) * * * * * * * * Output current Latch-up performance ESD performance Ultra-small package : IOHA/IOLA(A bus)=12mA(min)(VCC=3.0V) : IOHB/IOLB(B bus)=24mA(min)(VCC=3.0V) : 300mA : Machine model 200 V Human body model 2000 V : VSSOP(US20), VQON20 Bus hold circuit is built in only the B bus side.(Only in OE=H, a former state is maintained.) Floating of A-bus and B-bus are permitted.(When OE=H) Gate IC for control(TC7MP01FK) of DIR and OE terminal are prepared. 3.6V tolerant function provided on A-bus terminal, DIR and OE terminal. Note 1: At the time bus terminal is enable state, please do not give a signal from the outside. Note 2: When mounting VQON package, the type of recommended flux is RA or RMA. 1 2007-10-19 TC7MP245FK/FTG Pin Assighment (top view) FK (VSSOP20-P-0030-0.50) FTG (VQON20-P-0404-0.50) A1 DIR VCC 19 18 OE 17 B1 16 DIR A1 A2 A3 A4 A5 A6 A7 A8 1 2 3 4 5 6 7 8 9 20 VCC 20 19 18 17 16 15 14 13 12 11 OE B1 B2 B3 B4 B5 B6 B7 B8 A2 A3 A4 A5 A6 1 2 3 4 5 15 14 13 12 11 B2 B3 B4 B5 B6 6 A7 7 8 9 10 B7 A8 GND B8 GND 10 Truth Table Input Bus state DIR L H X OE L L H BA(B=A) AB(A=B) Z Bus hold circuit (B bus) OFF OFF ON* Marking FTG (VQON20-P-0404-0.50) P 0 0A **** 1 pin Product Name Lot trace code X: Don't care Z: High impedance *: Logic state just before becoming disable is maintained. Note: When a bus input is in "H" state ,and an output is switched to "enable" to "disable", Glitch such as "L" state during about 1 to 3ns occurs in an output. It is not generated when a bus input is in "L" state.

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).

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.
