1

Enable Input/Power Input. Drive high (> 2.5V) to enable; drive low (< 2.2V) to

disable. When disabled, SET, LED1, LED2, LED3 and LED4 are high impedance.

When enabled, EN is the power input for the T6311A.

3

Bias Current Set Input. The current flowing into SET sets the bias current into each

LED by ILED_= 240 x ISET. VSET is internally biased to 1.2V. SET is high

impedance when EN is low.

NC

-

No connection.

LED4

-

LED 4 Cathode Connection. Current flowing into LED4 is 240 times the current

flowing into SET. LED4 is high impedance when EN is low.

LED3

LED 3 Cathode Connection. Current flowing into LED3 is 240 times the current

flowing into SET. LED3 is high impedance when EN is low.

LED2

5

LED 2 Cathode Connection. Current flowing into LED2 is 240 times the current

flowing into SET. LED2 is high impedance when EN is low.

LED1

LED 1 Cathode Connection. Current flowing into LED1 is 240 times the current

flowing into SET. LED1 is high impedance when EN is low.
