PCAL9539A

16-bit I2C-bus and SMBus low power I/O port with interrupt and reset

[1]

For IDD, all typical values are at nominal supply voltage (1.8 V, 2.5 V, 3.3 V, 3.6 V or 5 V VDD) and Tamb =25 C. Except for IDD, the

typical values are at VDD = 3.3 V and Tamb =25 C.

[2]

The total current sourced by all I/Os must be limited to 160 mA.

[3]

Typical value for Tamb =25 C. VOL = 0.4 V and VDD = 3.3 V. Typical value for VDD <2.5 V, VOL =0.6 V.

[4]

Internal pull-up/pull-down resistors disabled.
