Dual supply translating transceiver; 3-state

10. Static characteristics

[1]

VCCO is the supply voltage associated with the output port.

[2]

VCCI is the supply voltage associated with the data input port.

[3]

To guarantee the node switches, an external driver must source/sink at least IBHLO/IBHHO when the input is in the range VIL to VIH.

Table 7.

Typical static characteristics at Tamb = 25 C

At recommended operating conditions; voltages are referenced to GND (ground = 0 V).
