| Manufacturer | NXP Semiconductors |
| Overview |
The PCF8574/74A provides general-purpose remote I/O expansion via the two-wire bidirectional I2C-bus (serial clock (SCL), serial data (SDA)).
The devices consist of eight quasi-bidirectional ports, 10.
and benefits
* I2C-bus to parallel port expander * 100 kHz I2C-bus interface (Standard-mode I2C-bus) * Operating supply voltage 2.5 V to 6 V with non-overvoltage tolerant I/O held to VDD with 100 A current source * 8-bit remote I/O pins that default to inputs at power-up * Latched outputs directly . |
