ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Junction Temperature of T A = 25°C only; limits applying over the full
Operating Ambient Temperature range are denoted by a “?”. Minimum and Maximum limits are guaranteed through test,
design, or statistical correlation. Typical values represent the most likely parametric norm at T A = 25°C, and are provided
for reference purposes only. Unless otherwise indicated, V CC = 2.7V to 5.5V, ENABLE = V CC , I LED = 15mA.

Difference between V CC voltage and LED anode voltage at which I LED current drops 10% from nominal value
I LED current variations per volt V CC change
I LED current variations at V D change from 0.15 to 1.0V
EN input voltage should not exceed V CC voltage at any condition
