TC7MZ240FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MZ240FK Low Voltage Octal Bus Buffer (inverted) with 5 V Tolerant Inputs and Outputs The TC7MZ240FK is a high performance CMOS octal bus buffer. Designed for use in 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. The device is designed for low-voltage (3.3 V) VCC applications, but it could be used to interface to 5 V supply environment for both inputs and outputs. The 7C7MZ240FK is an inverting 3-state buffer having two active-low output enables. This device is designed to be used with 3-state memory address drivers, etc. All inputs are equipped with protection circuits against static discharge. Weight: 0.03 g (typ.) Features * * * * * * * Low voltage operation: VCC = 2.0~3.6 V High speed operation: tpd = 6.5 ns (max) (VCC = 3.0~3.6 V) Output current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) Latch-up performance: -500 mA Package: VSSOP (US20) Power down protection is provided on all inputs and outputs.

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.
