CTM1051KT

ZLG Zhiyuan Elec · CAN Bus Modules · DIP-7

CTM1051KT from ZLG Zhiyuan Elec, in a DIP-7. 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 Vin power_in Module power input. Nominal 5.0 VDC (4.75 V min, 5.25 V max) for the CTM1051KT variant. Typical quiescent current 26 mA, max operating current 50 mA. A 10 uF bulk decoupling capacitor to GND is recommended.
2 GND power_in Input-side (controller-side) power ground reference. Common to Vin, TXD and RXD; isolated from CANG on the bus side.
3 TXD input CAN controller transmit data input from the host MCU CAN controller. Logic-level input: VIH >= 2 V, VIL <= 0.8 V (5 V family), drive current 2 mA minimum. Includes a dominant time-out (tto(dom) typ 1 ms) to prevent bus lockup.
4 RXD output CAN controller receive data output to the host MCU CAN controller. Push-pull logic-level output: VOH >= VCC-0.4, VOL <= 0.4 V, output current up to 10 mA. Referenced to input-side GND (pin 2).
6 CANH bidirectional CAN bus high signal line, isolated from the input side by 3500VDC. Dominant level typ 3.5 V, recessive typ 2.5 V. Withstands -58 V to +58 V continuous bus voltage and -150 V to +100 V transients. Complies with ISO/DIS 11898.
7 CANL bidirectional CAN bus low signal line, isolated from the input side by 3500VDC. Dominant level typ 1.5 V, recessive typ 2.5 V. Withstands -58 V to +58 V continuous bus voltage and -150 V to +100 V transients. Complies with ISO/DIS 11898.
8 CANG power_out Isolated bus-side ground reference (isolated power output ground). Reference return for the CANH/CANL bus side; per the typical application (Fig. 1) it is left floating in normal use, and tied to shield/earth only through the recommended surge protection network.
