I/o Expanders datasheet and documents for PCF8574DGVRG4

PCF8574DGVRG4

I/o Expanders Overview

The PCF8574DGVRG4 is an 8-bit I/O expander for the two-line bidirectional I2C bus, designed for VCC operation between 2.5V and 6V. It provides general-purpose remote I/O expansion via SCL and SDA pins, featuring an 8-bit quasi-bidirectional port (P0–P7) with latched outputs capable of directly driving LEDs. The device includes an open-drain interrupt output (INT) triggered by any rising or falling edge on the port inputs. It operates within a temperature range of -40°C to +85°C and utilizes a TVSOP-20 package.

I/o Expanders Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm compliance details and availability status. Ensure the component matches the required TVSOP-20 package dimensions and thermal characteristics for the target PCB layout. Cross-reference the part number with official distributor catalogs to validate authenticity and production lifecycle stage before procurement.

I/o Expanders Selection Notes

Select this component when GPIO resources are limited on the host microcontroller and low standby current consumption is required. Ensure the system voltage falls within the 2.5V to 6V operating range. Verify that the I2C bus capacitance does not exceed 400 pF for standard-mode operation. Confirm compatibility with the microcontroller's I2C interface timing requirements.

I/o Expanders Part Context

This component belongs to the PCF8574 family of remote 8-bit I/O expanders for the I2C bus. It is manufactured by Texas Instruments and serves as a solution for expanding I/O capabilities in systems with GPIO-limited processors. The device is compatible with most microcontroller families and offers a cost-effective method for adding peripheral control without additional complex interfaces.
