HEF4511B Description
The HEF4511B is a BCD to 7-segment latch/decoder/driver with four address inputs (DA to DD), an active LOW latch enable input (EL), an active LOW ripple blanking input (BI), an active LOW lamp test input (LT), and seven active HIGH n-p-n bipolar transistor segment outputs (Oa to Og). When EL is LOW, the state of the segment outputs (Oa to Og) is determined by the data on DA to DD. When EL goes HIGH, the last data...
