† _{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: 3. Meets TTL levels, VIO(min) = 2 V and VIH(max) = 0.8 V on nonhysteresis inputs.
4. Applies for external output buffers.
5. These junction temperatures reflect simulated conditions. Absolute maximum junction temperature is 150°C. The customer is
responsible for verifying junction temperature.
6. These parameters apply for D7–D0.
7. These parameters apply for DTRA, DTRB, INIA, INTB, RTSA, RTSB, RXRDYA, RXRDYB, TXRDYA, TXRDYB, TXA, TXB.
8. The internal oscillator cell can only support up to 24 MHz clock frequency to make the crystal oscillating when crystal is used. If
external oscillator or other on board clock source is used, the TL16C752B-EP can work for input clock frequency up to 48 MHz.
9. Measurement condition:
a) Normal operation other than sleep mode:
VCC = 3.3 V, TA = 25°C. Full duplex serial activity on all serial (UART) channels at the clock frequency specified in the
recommended operating conditions with divisor 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.
