Product Overview
BCD-to-7-segment latch/decoder/driver for LCD and LED displays; four BCD/data inputs, active-LOW latch enable, active-HIGH blanking and phase inputs, and seven buffered segment outputs.
It can directly implement the latch, BCD decode, blanking, and phase functions, but the low listed output currents mean high-current LED segments generally require external gain/driver devices. Nexperia explicitly shows added bipolar transistors where higher gain/current is needed.

Design Considerations
-
- Verify the display technology and common-anode/common-cathode/phase polarity against the required function table. 2. Check segment current against the stated output-current ratings; add external drivers where required. 3. Include load capacitance in the datasheet propagation-delay formulas. 4. Ensure input rise/fall rates remain within the voltage-dependent limits. 5. Tie unused inputs to VDD, VSS, or another valid input as specified.
Application Fit
Driving LCD, LED, fluorescent, incandescent, and gas-discharge displays.
