Hi Sir/Mdm,

The Vcc spec is narrower at 5V +/- 0.5% and what is the impact if the Vcc supply voltage drop to range 4.5V to 4.75V?

Jason,

The SN65LBC176A needs a minimum Vcc of 4.75V and maximum of 5.25V which is a tolerance of +/- 5%. We cannot guarantee that this device will function with Vcc less than 4.75. We have newer devices that can handle lower Vcc if that would be better for your application.

Respectfully,

Lucas Schulte
