HT42B534-1 USB to UART TTL Converter IC SMD SOP-8

HT42B534-1 USB to UART TTL Converter IC SMD SOP-8

The HT42B534-x device is a high performance USB to UART bridge controller with fully integrated USB and UART interface functions, designed for applications that communicate with various types of UART. The device includes a USB 2.0 full speed compatible interface which is used for PC communication. The device also includes a fully integrated high speed oscillator which is used as clock source for the USB and UART baud rate generator. The baud rate generator can support up to 3Mbps of baud rate for the UART interface.


  • Operating Voltage (VDD): 3.3V~5.5V
  • UART pins Voltage (VDDIO): 1.8V~VDD (Less than VDD voltage)
  • Power down and wake-up functions to reduce power consumption
  • Fully integrated internal 12MHz oscillator with 0.25% accuracy for all USB modes which requires no external components
  • USB interface
