ZHCSPC7B December 2022 – November 2023 TCA39416
PRODUCTION DATA
The A and B ports are able to accept I/O voltages ranging from 0.72 V to 1.98 V. VCCA must be ≤ VCCB to ensure proper operation. The device is a pass-gate architecture with edge-rate accelerators (one-shots) to improve the overall data rate and supports both high speed push-pull and low speed open-drain operation.
MIPI I3C specification requires dynamic pull-up control to switch between “strong pull-up” and “weak pull-up” to optimize open-drain and push-pull timing requirements. In TCA39416, the internal 10-kΩ pull-up resistors on Ax and Bx pins are enabled based on respective VCC voltage and OE input and act as High-Keeper when the bus is high.
When OE is low, the TCA39416 is disabled, the one shots and internal pull ups are also disabled.
