TC74HC4511AP Overview
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 mon 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...
