Features: • Low-voltage operation : VCC = 1.65 to 3.6 V
• 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 : ICC = 5A(max)(Vcc=3.6V)
• High-speed operation : tpd=3.0ns(max)(Vcc=3.3±0.3V)
tpd=4.6ns(max)(Vcc=2.5±0.2V)
tpd=10.0ns(max)(Vcc=1.8±0.15V)
• Output current : IOHA/IOLA(A bus)=±12mA(min)(VCC=3.0V)
: IOHB/IOLB(B bus)=±24mA(min)(VCC=3.0V)
• Latch-up performance : ±300mA
• ESD performance : Machine model ±200 V
Human body model ±2000 V
• Ultra-small package : 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: 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: VCC=0V, or output off state.
Note 3: OE="L", DIR="L"
DescriptionThe TC7MP245FTG 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 TC7MP245FTG 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 of TC7MP245FTG are equipped with protection circuits against static discharge.
