TCA9509RVHR Frequently Asked Questions (FAQ)
-
Texas Instruments recommends following a star topology for the signal lines, keeping them short and away from noise sources. Use a solid ground plane and decouple the device with a 0.1uF capacitor. Route the clock lines close to the return path to minimize loop inductance.
-
Ensure the device is operated within the recommended temperature range (-40°C to 85°C). Use a heat sink or thermal pad to dissipate heat. Reduce the clock frequency or use a lower power mode to reduce heat generation.
-
Use a series termination resistor (Rs) of 33-50 ohms for the outputs, and a parallel termination resistor (Rt) of 50-100 ohms for the clock output. This helps to reduce signal reflections and improve signal integrity.
-
Power up the device in the following sequence: VCC, then VCCIO, then apply the clock signal. Ensure the reset pin is held low during power-up and released after VCC and VCCIO are stable. Use a reset supervisor or a power-on reset circuit to ensure a clean reset.
-
Use ESD protection diodes or TVS diodes on the I/O lines. Ensure the device is handled and stored in an ESD-safe environment. Use a latch-up prevention circuit or a power-on reset circuit to prevent latch-up conditions.
