CTM1051MG

ZLG Zhiyuan Elec · CAN Bus Modules · DIP-7

CTM1051MG 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 RXD output CAN receive data output to the MCU. Logic high VOH >= VCC-0.4 V at IRXD = -1.5 mA; logic low VOL <= 0.4 V at IRXD = 1.5 mA. Maximum output current 10 mA.
2 TXD input CAN transmit data input from the MCU. Logic high VIH >= 0.7*VCC, logic low VIL <= 0.3*VCC. Internal ~10 kΩ pull-up to VCC; drive strength IT >= 2 mA. Dominant timeout tto(dom)TXD = 0.3 to 3.8 ms.
3 GND power_in Input-side power ground, referenced to the MCU/logic domain. Isolated from CANG by 2500 VDC.
4 VCC power_in Input-side power supply, +5 V nominal (4.75 to 5.25 VDC). Quiescent current ~9 mA typical, max operating current 90 mA.
5 CANG power_out Isolated output-side ground reference for the CAN bus. Typically left floating in simple applications; connected via shield/GDT/earth in surge-protected designs.
6 CANL bidirectional CAN bus low signal (ISO 11898-2 compliant). Dominant V(OD)CANL ~1.5 V, recessive ~2.5 V (no load). Bus pin max withstand -40 to +40 V; leakage +/-5 uA at VCC=0.
7 CANH bidirectional CAN bus high signal (ISO 11898-2 compliant). Dominant V(OD)CANH ~3.5 V, recessive ~2.5 V (no load). Differential dominant Vdiff(d) ~2 V into 60 Ω. Bus pin max withstand -40 to +40 V.
