Frequently Asked Questions
What displays can the 74HC/HCT4511 drive?
It can drive common cathode LED, incandescent, fluorescent, LCD, and gas discharge displays.
How does the latch store BCD inputs?
When LE is LOW, outputs follow D to D. When LE goes HIGH, the last data are stored and outputs stay stable.
What is the IC's guaranteed drive capability?
It has a guaranteed 10 mA drive capability per output and is categorized as MSI.
How do I use the lamp test feature?
Set the active LOW LT input to LOW; all segment outputs will go HIGH regardless of other inputs.
