TC7MA138FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC7MA138FK Low Voltage 3-to-8 Line Decoder with 3.6 V Tolerant Inputs and Outputs The TC7MA138FK is a high performance CMOS 3-to-8 decoder which is guaranteed to operate from 1.2-V to 3.6-V. Designed for use in 1.5 V, 1.8 V, 2.5 V or 3.3 V systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. When the device is enabled, 3 binary select inputs (A, B and C) determine which one of the outputs ( Y0 to Y7 ) will go low. When enable input G1 is held low or either G2A or G2B is held high, decoding function is inhibited and all outputs go high. Weight: 0.02 g (typ.) G1, G2A and G2B inputs are provided to ease cascade connection and for use as an address decoder for memory systems. All inputs are equipped with protection circuits against static discharge.

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: VCC = 0 V Note 3: High or low state. IOUT absolute maximum rating must be observed.
