Product Overview
PCA9574PW,118 is an 8-bit I²C-bus and SMBus, level translating, low voltage GPIO with reset and interrupt. It is a CMOS device that provides 8 bits of general-purpose parallel input/output (GPIO) expansion in low voltage processors and handheld battery-powered mobile applications and was developed to enhance the NXP family of I²C-bus I/O expanders. The improvements include lower supply current, lower operating voltage of 1.1V to 3.6V, dual and separate supply rails to allow voltage level translation anywhere between 1.1V and 3.6V, 400KHz clock frequency, and smaller packaging. Any of the eight I/O ports can be configured as an input or output independent of each other and default on start-up to inputs. The application includes cell phones, media players, multi-voltage environments, battery-operated mobile gadgets, motherboards, servers, RAID systems, industrial control, medical equipment, PLCs, gaming machines, instrumentation, and test measurement.
- 400KHz I²C-bus serial interface, compliant with I²C-bus standard-mode (100KHz)
- Separate supply rails for core logic and I/O bank provides voltage level shifting
- 1.1V to 3.6V operation with level shifting feature, very low standby current is
1μA - 8 configurable I/O pins that default to inputs at power-up
- Independently programmable 100kohm pull-up or pull-down for each I/O pin
- Open-drain active low INT o/p pin allows monitoring of logic level change of pins programmed as i/ps
- Programmable bus hold provides valid logic level when inputs are not actively driven
- Active LOW reset (RESET, active low) input pin resets device to power-up default state
- ESD protection exceeds 7000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
- TSSOP16 package, ambient temperature range from -40°C to +85°C
