PCA9571

Remote 8-bit general purpose outputs for 1 MHz I²C-bus

Rev. 1 — 22 December 2014

Product data sheet

1. General description

The PCA9571 is a CMOS device that provide 8 bits of General Purpose parallel Output

(GPO) expansion in low voltage processor and handheld battery powered mobile

applications. They operate at 1 MHz I²C-bus speeds on a lightly loaded bus (<100 pF)

while maintaining backward compatibility to Fast-mode (400 kHz) and Standard-mode

(100 kHz).

The PCA9571 is a streamlined GPO that consists of 8-bit push-pull outputs that offer low

current consumption, small packaging options and a low operating voltage range of 1.1 V

to 3.6 V. The latched outputs are symmetrical 4 mA current drive capability at 3.3 V to

drive various control logic. The PCA9571 output expanders provide a simple solution

when additional outputs are needed while keeping interconnections and floor space to a

minimum, for example, in battery powered mobile applications where PCBs are crowded

for interfacing to sensors, push buttons, etc.

The PCA9571 contains an internal Power-On Reset (POR) and a Software Reset feature

that initializes the device to its default state.

2. Features and benefits

 1 MHz I²C-bus interface with 6 mA SDA sink capability for lightly loaded buses

(<100 pF) and improved power consumption

 Compliant with the I²C-bus Fast and Standard modes

 1.1 V to 3.6 V operation

 Latched outputs with a sink/source capability of 4 mA at 3.3 V

 Readable device ID (manufacturer, device type, and revision)

 Software Reset

 Power-On Reset

 Low standby current

 40 C to +85 C operation

 ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per

JESD22-C101

 Latch-up testing is done to JEDEC standard JESD78 which exceeds 100 mA

 Packages offered: XQFN12, TSSOP14 and DHVQFN14

3. Applications

 Smartphones and tablets

 Portable medical equipment

 Portable instrumentation and test measurement
