The HEF4511B is a BCD to 7-segment latch/decoder/driver with four address inputs (D0 to D3), an active HIGH latch enable input (LE), an active LOW ripple blanking input (BL), an active LOW lamp test input (LT), and seven active HIGH NPN bipolar transistor segment outputs (Qa to Qg).

When LE is LOW and BL is HIGH, the state of the segment outputs (Qa to Qg) is determined by the data on D0 to D3. When LE goes HIGH, the last data present on D0 to D3 is stored in the latches and the segment outputs remain unchanged. When LT is LOW, all of the segment outputs are HIGH independent of all other input conditions. With LT HIGH, a LOW on BL forces all segment outputs LOW. The inputs LT and BL do not affect
the latch circuit.

It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.
