TC7MP245FK/FTG
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7MP245FK, TC7MP245FTG
Low-Voltage/Low-Power Octal Bus Transceiver with Bus-hold
TC7MP245FK
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.

Weight:
VSSOP20-P-0030-0.50 : 0.03 g (typ.)
VQON20-P-0404-0.50 : 0.0145 g (typ.)
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 = 5μA(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)
: IOHA/IOLA(A bus)=±12mA(min)(VCC=3.0V)
: IOHB/IOLB(B bus)=±24mA(min)(VCC=3.0V)
: ±300mA

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: 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.

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.

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).
