TCAN1044AVDDFRQ1

Texas Instruments · CAN Transceivers · TSOT-23-8

TCAN1044AVDDFRQ1 from Texas Instruments, in a TSOT-23-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 TXD input CAN transmit data input; VIH ≥ 0.7×VIO, VIL ≤ 0.3×VIO; integrated pull-up.
2 GND power_in Ground connection and voltage reference for all measurements.
3 VCC power_in 5V supply voltage; recommended operating range 4.5V to 5.5V.
4 RXD tri_state CAN receive data output; VOH = 0.8×VIO, VOL = 0.2×VIO; tri-stated when device powered off.
5 VIO power_in I/O supply voltage for logic level shifting; 1.7V to 5.5V range supports 1.8V, 2.5V, 3.3V, and 5V logic systems.
6 CANL bidirectional CAN low differential bus line; ±12V common-mode input range, ±58V bus fault protection, 40kΩ to 90kΩ differential input resistance.
7 CANH bidirectional CAN high differential bus line; ±12V common-mode input range, ±58V bus fault protection, ISO 11898-2:2016 compliant.
8 STB input Standby mode control input; high enables low-power standby mode with wake-up detection, low enables normal mode; integrated pull-up.
