Philips Semiconductors Product specification BCD to 7-segment latch/decoder/driver 74HC/HCT4511 ripple blanking input (BI), an active LOW lamp test input (LT), and seven active HIGH segment outputs (Qa to Qg). FEATURES • Latch storage of BCD inputs 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.
