Product Overview
PCA9535CHF,118 is a 16bit I²C-bus and SMBus, low power I/O port with interrupt CMOS device. It provides 16 bits of general purpose parallel input/output expansion for I²C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I²C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc. It consists of two 8-bit configuration (input or output selection), input, output and Polarity inversion registers. Data for each input or output is kept in corresponding input or output register. The polarity of the read register can be inverted with Polarity inversion register. It is identical to the PCA9555 except for the removal of the internal I/O pull-up resistor which greatly reduces power consumption when the I/Os are held LOW.
- 5V tolerant I/Os, Polarity inversion register, active LOW interrupt output
- Low standby current, noise filter on SCL/SDA inputs
- No glitch on power-up, internal power-on reset
- 16 I/O pins which default to 16 inputs, 0Hz to 400KHz clock frequency range
- ESD protection exceeds 2000V HBM per JESD22-A114, 200V MM per JESD22-A115, 1000V CDM per JESD22-C101
- Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100mA
- Supply voltage range from 2.3 to 5.5V (VSS = 0V, Tamb = -40°C to +85°C)
- Standby current is 0.25µA typ (standby mode, VDD = 5.5V, no load, VI=VSS; fSCL = 0KHz, I/O = input)
- Power-on reset voltage is 1.7V typ (no load; VI = VDD or VSS, Tamb = -40°C to +85°C)
- HWQFN24 package, ambient temperature range from -40°C to +85°C
