ماژول مبدل سطح TXB0104 یک مبدل ولتاژ دو طرفه با قابلیت دریافت ورودی 4 بیتی است. این ماژول دارای دو پورت A , B برای ولتاژ در دو سطح می باشد و هر کدام به ترتیب در محدوده 1.2 تا 3.6 ولت روی پورت A و در محدوده 1.65 تا 5.5 ولت عمل می کند.
این ماژول لول شیفتر از محصولات CJMCU است و می تواند طوری تنظیم شود تا از جریان برگشتی در حالت ولتاژ پایین محافظت شود و همچنین قابلیت ESD Protection نیز دارد.

دیتاشیت چیپ TXB0104 CJMCU
This 4-bit non-inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V,1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.
When the output-enable (OE) input is low, all outputs are placed in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver. The TXB0104 is designed so that the OE input circuit is supplied by VCCA.
This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
