PCA9574BS - Brand New NXP Semiconductors I/O Expanders
-
Description
The PCA9574BS is a CMOS device that provides 8 bits of General Purpose parallel Input/Output (GPIO) expansion in low voltage processor and handheld battery powered mobile applications. It was developed to enhance the NXP family of I2C-bus I/O expanders and offers improvements such as lower supply current, lower operating voltage of 1.1 V to 3.6 V, dual and separate supply rails for voltage level translation, 400 kHz clock frequency, and smaller packaging. The PCA9574BS simplifies interconnection of a processor running at one voltage level to I/O devices operating at a different voltage level, making it suitable for battery powered mobile applications and clamshell devices. It also features built-in level shifting for compatibility with mixed signal environments. The core of the PCA9574BS operates at a voltage as low as 1.1 V, while the I/O bank can operate between 1.1 V and 3.6 V. It also includes bus hold with programmable on-chip pull-up or pull-down feature for I/Os.
Specifications and features
- 400 kHz I2C-bus serial interface
- Compliant with I2C-bus Standard-mode (100 kHz)
- Separate supply rails for core logic and I/O bank provides voltage level shifting
- 1.1 V to 3.6 V operation with level shifting feature
- Very low standby current: < 1 µA
- 8 configurable I/O pins that default to inputs at power-up
- Outputs:
♦ Totem pole: 1 mA source and 3 mA sink
♦ Independently programmable 100 kΩ pull-up or pull-down for each I/O pin
♦ Open-drain active LOW interrupt (INT) output pin allows monitoring of logic level change of pins programmed as inputs- Inputs:
♦ Programmable bus hold provides valid logic level when inputs are not actively driven
♦ Programmable Interrupt Mask Control for input pins that do not require an interrupt when their states change or to prevent spurious interrupts default to mask at power-up
♦ Polarity inversion register allows inversion of the polarity of the I/O pins when read- Active LOW reset (RESET) input pin resets device to power-up default state
- GPIO All Call address allows programming of more than one device at the same time with the same parameters
- 2 programmable slave addresses using 1 address pin
- Operating temperature: -40 °C to +85 °C
- ESD protection exceeds 7000 V HBM per JESD22-A114, 500 V MM per JESD22-A115, and 1000 V CDM per JESD22-C101
