| TC74HC4511AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC4511AP,TC74HC4511AF BCD-to-7 Segment Latch/Decoder/Driver The TC74HC4511A is a high speed CMOS BCD-TO-7 SEGMENT LATCH/DECODER/DRIVER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The segment output driver, which is of CMOS construction, has a large IOH capability which permits the device to drive cathode common LED directly. When lamp test (LT) is held low, all segment outputs will go high, and when the blanking input (BI) is held low and LT is held high, all segment outputs will go low. These functions are independent of other inputs and used to test the display. BI is used to pulse - modulate the brightness of the display. When error code (over 10) is applied to BCD inputs, all segment outputs will go to low (turn off). All inputs are equipped with protection circuits against static discharge or transient excess voltage.

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 65C. From Ta = 65 to 85C a derating factor of -10 mW/C shall be applied until 300 mW.
