(2) Applies for external output buffers.
(3) These parameters apply for D7–D0.
(4) These parameters apply for DTRA, DTRB, INIA, INTB, RTSA, RTSB, RXRDYA, RXRDYB, TXRDYA, TXRDYB, TXA, TXB.
(5) These junction temperatures reflect simulated conditions. Absolute maximum junction temperature is 150°C. The customer is
responsible for verifying junction temperature.
(6) 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 can work for input clock frequency up to 48 MHz.
(7) Measurement condition:
(a) Normal operation other than sleep mode: V
CC
= 3.3 V, T
A
= 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: V
CC
= 3.3 V, T
A
= 25°C. After enabling the sleep mode for all four channels, all serial and host activity is kept idle.
