TC74VHC157FK(EL,K)

TC74VHC157F/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74VHC157F, TC74VHC157FK Quad 2-Channel Multiplexer The TC74VHC157 is an advanced high speed CMOS QUAD 2CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. It consists of four 2-input digital multiplexers with common select and strobe inputs. When the STROBE 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. An Input protection circuit ensures that 0 to 5.5 V can be applied to the input pins without regard to the supply voltage. This device can be used to interface 5 V to 3 V systems and on two supply systems such as battery back up. This circuit prevents device destruction due to mismatched supply and input voltages.

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). © 2019 Toshiba Electronic Devices & Storage Corporation 3 2019-01-31 TC74VHC157F/FK Operating Ranges (Note) Characteristics Symbol Rating Unit Supply voltage VCC 2.0 to 5.5 V Input voltage VIN 0 to 5.5 V VOUT 0 to VCC V Operating temperature Topr −40 to 85 °C Input rise and fall time dt/dv 0 to 100 (VCC = 3.3 ± 0.3 V) 0 to 20 (VCC = 5 ± 0.5 V) ns/V Output voltage Note: The operating ranges must be maintained to ensure the normal operation of the device.
