74HC/HCT4511 is a high-speed BCD to 7-segment latch/decoder/driver with 10mA drive capability, can drive common cathode LED displays.
The 74HC/HCT4511 is a high-speed Si-gate CMOS device designed as a BCD to 7-segment latch/decoder/driver. It features four address inputs, an active LOW latch enable input, an active LOW ripple blanking input, and an active LOW lamp test input. The device drives common cathode LED displays with a guaranteed 10 mA drive capability per output.
| Drive capability per output | 10 mA |
|---|---|
| Logic category | MSI |
| Propagation delay (Dn to Qh) | 24 ns typical |
| Input capacitance | 3.5 pF |
When LT is LOW, all segment outputs are HIGH regardless of other inputs.
A LOW on BI forces all segment outputs LOW to blank the display.
