TC74ACT157P/F/FN/FT TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74ACT157P,TC74ACT157F,TC74ACT157FN,TC74ACT157FT Quad 2-Channel Multiplexer The TC74ACT157 is an advanced high speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levles. This device consist of four 2-input digital multiplexer with common select and strobe inputs. When the ST input is held “H” level, selection of data is inhibited and all the outputs become “L” level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding 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 should be applied up to 300 mW. 3 2007-10-01 TC74ACT157P/F/FN/FT Operating Ranges (Note) Characteristics Supply voltage Input voltage Output voltage Operating temperature Input rise and fall time Symbol VCC VIN VOUT Topr dt/dV Rating 4.5 to 5.5 0 to VCC 0 to VCC −40 to 85 0 to 10 Unit V V V °C ns/V Note: The operating ranges must be maintained to ensure the normal operation of the device.
