TC7WZ245FU/FK
TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic
TC7WZ245FU, TC7WZ245FK
Dual Bus Transceiver
Features
High output current
: ±24mA (min) at VCC = 3V
Super high speed operation : tpd = 5.0ns (max)
at VCC = 5V, 50 pF
Operation voltage range : VCC (opr) = 1.65 to 5.5V
5.5-V tolerant inputs
5.5-V power down protection outputs
Matches the performance of TC74LCX series when operated at
3.3-V VCC
Note: Do not apply a signal to any pins when it is the output
mode. Damage may result.
All floating (high impedance) bus pins must have their input
levels fixed by means of pull-up or pull-down resistors.

Note:
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 1: VCC = 0V or High impedance condition
Note 2: High or Low state. Do not exceed IOUT of absolute maximum ratings.
Note 3: VOUT < GND
