TIOL112YAHR TI I/O Expander | 12-DSBGA-2.45X1.7 | 1.65V-5.5V, 12 GPIO

Product Overview

The TIOL112YAHR is a 12-bit I/O expander from Texas Instruments, designed for I²C/SMBus interface applications. It provides 12 general-purpose input/output (GPIO) pins with interrupt and reset functions. Housed in a compact 12-DSBGA-2.45X1.7 package, it operates over a wide voltage range of 1.65V to 5.5V, making it suitable for low-power and portable devices. The device features a programmable interrupt output, open-drain active-low reset input, and configurable I/O direction. It supports standard (100 kHz) and fast (400 kHz) I²C bus frequencies.
