Details
Features ● Lower open-loop current consumption; IS <1 mA ● Lower output saturation voltage ● The temperature dependence of the switching distance is lower and compensation of the resonant circuit TC (temperature coefficient) is easier ● The sensitivity is higher, so that larger switching distances are possible and coils of a lower quality can be used ● The switching hysteresis remains constant as regards temperature, supply voltage and switching distance ● The TCA 305 even functions without external integrating capacitor. With an external capacitor (or with RC combination) good noise immunity can be achieved ● The outputs are temporarily short-circuit proof (approx. 10 s to 1 min depending on package) ● The outputs are disabled when VS

FAQs
What is TCA355?
The TCA355 is a dual channel buffer with voltage translation capability designed by Texas Instruments. It is ideal for level-shifting applications, I2C bus buffering, and voltage translation between different logic levels.
How Does TCA355 Work?
The TCA355 works by providing bidirectional voltage level translation between two independent power supply rails. It features two non-inverting channels with integrated direction control, allowing seamless translation of logic levels without the need for additional circuitry. The device can operate at high-speed rates, making it suitable for applications requiring fast data transfer.
How Many Pins does TCA355 have and What are the Functions of the Pinout Configuration?
The TCA355 is housed in a 10-pin VSSOP (Very Small Outline Package) package. The pinout configuration includes:
- A port: Channel A data input/output and control pins.
- B port: Channel B data input/output and control pins.
- Dir: Direction control pin.
- VCCA, VCCB: Power supply pins for each channel.
- GND: Ground pin.
What are the Pros and Cons of TCA355?
Pros:
- Level Translation: Provides bidirectional voltage level translation for seamless interfacing between different logic levels.
- Integrated Direction Control: Simplifies the interface with automatic direction detection.
- High-Speed Operation: Suitable for applications requiring fast data transfer rates.
- Compact Package: The VSSOP package offers a space-efficient footprint for compact designs.
Cons:
- Complexity: May require careful consideration of signal integrity and layout for optimal performance.
- Additional Components: External decoupling capacitors may be needed for stable operation in certain applications.
Are There Any Equivalents/Alternatives to TCA355 for Recommendation?
- The TXB0102 from Texas Instruments is a similar dual-channel voltage level translator with automatic direction sensing.
- Alternatives to the TCA355 include the PCA9306 from NXP Semiconductors and the SN74LVC2T45 from Texas Instruments.
