Description

TCA9517DGKRQ1 – TI

Description

The TCA9517 is a dual-supply, dual-bidirectional voltage translator for open-drain and push-pull applications. It supports up to 2.5 Mbps of UART interface and 1.6 Mbps for the I2C-bus interface. The device provides a high-impedance state on one side of the device when either side is powered down. The low power consumption of the TCA9517 makes it an ideal solution for battery-powered, handheld, and portable applications.
