9.1 Application Information

The SN74LV6T07 can be used to drive LEDs with control from very low voltage sources. The supply voltage of the SN74LV6T07 can be set as low as 1.8 V (±0.15 V), which allows for controlling an LED powered by up to 5 V with an input voltage as low as 1.2 V. As an example, with a 1.8 V SN74LV6T07 supply voltage, the output of the SN74LV6T07 is expected to have an equivalent low-state resistance of 30 Ω (ROL = VOL / IOL = 0.15 V / 5 mA, from the Typical Characteristics). Therefore the calculation of the current limiting resistor is:

Equation 1. R 1 = V P U - V F I D - 30

with VPU shown in Equation 1 as the diode pull-up voltage (separate from the device supply voltage, VCC), VF as the diode forward voltage, and ID as the desired diode current.
