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: Output in off-state
Note 3: High or low state. IOUT absolute maximum rating must be observed.
Note 4: V_OUT < GND, V_OUT > V_CC




Description

The TC7MZ245FK is a high performance CMOS octal bus transceiver. Designed for use in 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

The TC7MZ245FK is designed for low-voltage (3.3 V) V_CC applications, but it could be used to interface to 5 V supply environment for both inputs and outputs.

The direction of data transmission is determined by the level of the DIR input. The enable input (OE ) of TC7MZ245FK can be used to disable the device so that the busses are effectively isolated.

All inputs of TC7MZ245FK are equipped with protection circuits against static discharge.
