PCA9674TS,118

I/o Expanders Overview

The PCA9674TS,118 is an 8-bit remote I/O expander for the Fast-mode Plus (Fm+) I2C-bus. It features a 1 MHz interface with SDA sink capability of 30 mA and operates on a supply voltage range of 2.3 V to 5.5 V. The device provides latched outputs with 25 mA sink current per pin and a total package sink capability of 200 mA. It includes an active LOW open-drain interrupt output and supports 64 programmable slave addresses via three hardware address pins. The typical static standby current is 4.5 µA, and it functions within an ambient temperature range of -40 °C to +85 °C.

I/o Expanders Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and tape-and-reel specifications. Confirm that the component meets all required environmental standards and RoHS compliance levels before finalizing procurement orders.

I/o Expanders Selection Notes

Select this component when high-speed Fm+ I2C communication at 1 MHz is required alongside direct LED drive capabilities. Ensure the system design accommodates the 2.3 V to 5.5 V operating voltage range and utilizes the available 64 unique addresses for bus expansion without requiring additional buffers.

I/o Expanders Part Context

This part belongs to the PCA9674 family of remote I/O expanders designed for Fm+ I2C-bus applications. It serves as a functional upgrade to older PCF8574 series devices by offering higher bus speeds and greater drive currents. The TS suffix indicates the TSSOP16 plastic thin shrink small outline package variant.
