† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:
1. Meets TTL levels, VIH(min) = 2 V and VIL(max) = 0.8 V on nonhysteresis inputs.
2. Applies for external output buffers.
3. These junction temperatures reflect simulated conditions. Absolute maximum junction temperature is 150°C. The customer is
responsible for verifying junction temperature.
4. These parameters apply for D7–D0.
5. These parameters apply for DTRA, DTRB, DTRC, DTRD, INTA, INTB, INTC, INTD, RTS_A, RTS_B, RTS_C, RTS_D, RSRDY,
TXRDY, TX_A, TX_B, TX_C, TX_D.
6. Measurement condition:
a) Normal operation other than sleep mode
VCC = 3.3 V, TA = 25°C.
Full duplex serial activity on all four serial (UART) channels at the clock frequency specified in above table with divisior of one.
b) Sleep mode
VCC = 3.3 V, TA = 25°C.
After enabling the sleep mode for all four channels, all serial and host activity is kept idle.
