2 Description
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.
