CTM1051M

YLPTEC · CAN Bus Modules · DIP-7

CTM1051M from YLPTEC, 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 Receive data output to the host CAN controller. Push-pull logic output referenced to VCC (5V); VOH ≥ VCC-0.4V, VOL ≤ 0.4V at IRXD = 4 mA. Drives a dominant-low / recessive-high signal to the MCU's CAN RX pin.
2 TXD input Transmit data input from the host CAN controller. 5V logic input: VIH ≥ 0.7·VCC, VIL ≤ 0.3·VCC; input drive current ITXD ≈ 2 mA. A low level drives the bus dominant; high level allows recessive. Dominant-timeout protection Tto(dom) 0.3-12 ms (typ 1 ms). Does not accept 3.3V logic - use CTM1051AM for 3.3V systems.
3 GND power_in Logic-side (input) power return. Reference ground for VCC, TXD and RXD. Galvanically isolated from the bus-side CANG return by 2500VDC (test 3500VDC).
4 VCC power_in Logic-side supply input, 5 V nominal (4.75-5.25 V, abs max 7 V, min -0.7 V). Powers the on-board isolated DC-DC as well as the transceiver logic side. Typical quiescent 35 mA, max operating 90 mA. No reverse-polarity protection - do not reverse VCC/GND.
5 CANG power_out Isolated-side return (bus-side ground) generated by the internal isolated DC-DC. Used as the local reference for CANH/CANL and as the tie point for shielded-twisted-pair inner shield in double-shield installations. Leave floating if not used (per §8.2).
6 CANL bidirectional CAN bus low-side differential line, ISO 11898-2 compliant. Dominant V(OD)CANL 0.5-2.25 V (typ 1.5 V), recessive V(OR)CANL 2-3 V (typ 2.5 V). Bus pin absolute range -58 V to +58 V, transient -150 V to +100 V. Connect to the CANL wire of the twisted pair; terminate the network with 120 Ω between CANH and CANL at each end.
7 CANH bidirectional CAN bus high-side differential line, ISO 11898-2 compliant. Dominant V(OD)CANH 2.75-4.5 V (typ 3.5 V), recessive V(OR)CANH 2-3 V (typ 2.5 V). Bus pin absolute range -58 V to +58 V, transient -150 V to +100 V. Connect to the CANH wire of the twisted pair; terminate the network with 120 Ω between CANH and CANL at each end.

CAD (KiCad official)

  • Symbol: CTM1051M
  • Footprint: Package_DIP:DIP-8-N6_W7.62mm
  • 3D model: DIP-7 (KiCad packages3D, STEP)
  • 3D model files: ctm1051m-etched.step / ctm1051m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ctm1051m.step / ctm1051m.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: YLPTEC datasheet (5 pp, sha256 8cbffb30decdc8a1, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
