Philips HEF4511B BCD to 7‑Segment Latch/Decoder/Driver Datasheet
The HEF4511B integrates a BCD to 7‑segment latch, decoder and driver in a single MSI device. It features four address inputs (Da‑Dp), an active‑LOW latch enable (EL), an active‑LOW ripple‑blanking input (BI) and an active‑LOW lamp‑test input (LT). The segment outputs are driven by n‑p‑n bipolar transistors and can source up to 25 mA.
Typical applications include driving LED, incandescent, fluorescent, gas‑discharge and LCD displays. The datasheet provides detailed pin‑out, electrical characteristics, timing diagrams and recommended connection circuits for various display types.
