TC74HC157,158AP/AF/AFN TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC157AP,TC74HC157AF,TC74HC157AFN TC74HC158AP,TC74HC158AF,TC74HC158AFN TC74HC157AP/AF/AFN Quad 2-Channel Multiplexer TC74HC158AP/AF/AFN Quad 2-Channel Multiplexer (inverting) The TC74HC157A and TC74HC158A are high speed CMOS 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology. They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC158A is an inverting multiplexer while the TC74HC157A is a non-inverting. When STROBE is held high, selection of data is inhibited and all the outputs become low in the case of HC157A or high in the case of HC158A. The SELECT decoding determines whether the A or B inputs get transferred to their corresponding Y ( Y ) outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. Note: xxxFN (JEDEC SOP) is not available in Japan.

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: 500 mW in the range of Ta = −40 to 65°C. From Ta = 65 to 85°C a derating factor of −10 mW/°C shall be applied until 300 mW.
