74HCT4511N

The 74HCT4511N is a BCD to 7-segment Latch/Decoder/Driver pin compatible with 4511 of the 4000B series. It has four address inputs (D1 to D4), an active low latch enable input (LE\), an active low ripple blanking input (BI\), an active low lamp test input (LT\) and seven active high segment outputs (Qa to Qg). When LE\ is low, the state of the segment outputs (Qa to Qg) is determined by the data on D1 to D4. When LE\ goes high, the last data present on D1 to D4 are stored in the latches and the segment outputs remain stable. When LT\ is low, all the segment outputs are high independent of all other input conditions. With LT\ high, a low on BI\ forces all segment outputs low. The inputs LT\ and BI\ do not affect the latch circuit.
