CD74HC4511 Overview
The CD54HC4511, CD74HC4511, and CD74HCT4511 are BCD-to-7 segment latch/decoder/ drivers with four address inputs (D0−D3), an activelow blanking (BL) input, lamp-test (LT) input, and a latch-enable (LE) input that, when high, enables the latches to store the BCD inputs. When LE is low, the latches are disabled, making the outputs transparent to the BCD inputs. Display An IMPORTANT NOTICE at the end of this data sheet...
