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: V_CC = 0 V
Note 3: High or low state. IOUT absolute maximum rating must be observed.
Note 4: V_OUT < GND, V_OUT > V_CC


Description

The TC7MA244FK is a high performance CMOS octal bus buffer which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation.

TC7MA244FK is also designed with over voltage tolerant inputs and outputs up to 3.6 V.

The TC7MA244FK is non-inverting 3-state buffer having four active-low output enables. When the OE input is high, the outputs are in a high impedance state. This device is designed to be used with 3-state memory address drivers, etc.

All inputs of TC7MA244FK are equipped with protection circuits against static discharge.
