description/ordering information
The CD54HC4511, CD74HC4511, and CD74HCT4511 are BCD-to-7 segment latch/decoder/drivers with four
address inputs (D
0
−D
3
), an active-low 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.
These devices have standard-size output transistors, but are capable of sourcing (at standard V
OH
levels) up
to 7.5 mA at 4.5 V. The HC types can supply up to 10 mA at 6 V.
