ESD2CAN24DCKRQ1

TEXAS INSTRUMENTS · Global Sourcing Parts · SC-70-3

ESD2CAN24DCKRQ1 from TEXAS INSTRUMENTS, in a SC-70-3. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO1 bidirectional ESD-protected bidirectional I/O that clamps to GND, rated for ISO 10605 ±27kV contact and air-gap discharge (330pF/330Ω), 5.7A IEC 61000-4-5 8/20µs surge, and ±24V reverse standoff voltage.
2 IO2 bidirectional ESD-protected bidirectional I/O that clamps to GND, rated for ISO 10605 ±27kV contact and air-gap discharge (330pF/330Ω), 5.7A IEC 61000-4-5 8/20µs surge, and ±24V reverse standoff voltage.
3 GND power_in Ground reference for the ESD clamp; the layout guidance calls for a thick, short return trace when pin 3 is grounded.
