USB 2.0 Full-Speed Transceiver with UART
Multiplexing Mode
ELECTRICAL CHARACTERISTICS (continued)
(VBUS = +4.0V to +5.5V, VUART = +2.7V to +3.3V, VL = +1.40V to +2.75V, TA = -40°C to +85°C, unless otherwise noted. Typical val-
ues are at VBUS = +5V, VL = +1.8V, VUART = +2.75V (UART Mode), and TA = +25°C.) (Note 1)
