TCAL6408RSVR TI I/O Expanders

The TCAL6408RSVR is an 8-bit I2C-bus and SMBus I/O expander from Texas Instruments featuring Agile I/O ports with enhanced I/O performance in terms of speed, power consumption, and EMI. The device operates with dual power supplies: 1.08V to 3.6V on the I2C bus side (VCCI) and 1.08V to 3.6V on the P-port side (VCCP), allowing bidirectional voltage-level translation and GPIO expansion between 1.2V, 1.8V, 2.5V, and 3.3V systems. The device supports 100-kHz (Standard-mode), 400-kHz (Fast-mode), and 1-MHz (Fast-mode Plus) I2C clock frequencies. Key features include programmable output drive strength for optimizing EMI and power consumption, programmable pull-up and pull-down resistors on each I/O, latchable inputs for glitch filtering, maskable interrupt with interrupt status register, programmable open-drain or push-pull outputs, and low standby current consumption of 1 µA typical at 1.8V. Housed in a 16-pin UQFN (RSV) package (2.6mm × 1.8mm), it operates over -40°C to 125°C. Applications include servers, routers, personal computers, personal electronics, industrial automation, gaming consoles, and products with GPIO-limited processors requiring advanced I/O configuration capabilities.
