NCA9700DQJ

Translators, Level Shifters Overview

The NCA9700DQJ is a dual-channel bidirectional repeater for I2C and SMBus/PMBus applications, targeting Fast-mode Plus (Fm+) protocols. It enables true 1 MHz operation without violating timing specifications through integrated edge accelerators that speed up LOW-to-HIGH transitions. The device supports voltage level translation between 1.08 V and 3.6 V on both ports A and B. It features integrated 4.3 kΩ pull-up resistors at each I/O pin, eliminating the need for external components. The IC utilizes Schmitt trigger inputs to filter noise and employs slew-controlled negative edges to reduce EMI.
