PCF8574DGVR Description

Short technical summary and product information.

The Texas Instruments PCF8574DGVR is an 8-bit input/output expander for the I2C bus, providing remote I/O expansion for microcontroller families. It operates with a supply voltage range of 2.5V to 6V and supports a maximum clock frequency of 100 kHz.

 

This device features an 8-bit quasi-bidirectional I/O port that can function as either an input or output without requiring a data-direction control signal. The outputs are latched and offer high-current drive capability, suitable for directly driving LEDs. An open-drain interrupt output is also included, which is compatible with most microcontrollers. The operating temperature range is -40°C to 85°C.

 

The PCF8574DGVR is available in a 20-TVSOP surface-mount package. It exhibits low standby-current consumption, typically 10µA maximum. The latch-up performance exceeds 100mA per JESD 78, Class II standards.
