PCA9570  
Remote 4-bit general purpose outputs for 1 MHz I2C-bus  
Rev. 5 — 16 November 2017  
Product data sheet  
1. General description  
The PCA9570 is a CMOS device that provides 4 bits of General Purpose parallel Output  
(GPO) expansion in low voltage processor and handheld battery powered mobile  
applications. It operates at 1 MHz I2C-bus speeds while maintaining backward  
compatibility to Fast-mode (400 kHz) and Standard-mode (100 kHz).  
The PCA9570 is a streamlined GPO that consists of 4-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 PCA9570 output expander provides 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 PCA9570 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: XQFN8 (0.5 mm lead pitch)  
3. Applications  
Smart phones and tablets  
Portable medical equipment  
Portable instrumentation and test measurement
