RS2T45XM

Jiangsu RUNIC Tech · Gates · MSOP-8

RS2T45XM from Jiangsu RUNIC Tech, in a MSOP-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 VCCA power_in A-port supply voltage rail. Recommended operating range 1.65V ≤ VCCA ≤ 5.5V. DIR input threshold is referenced to VCCA.
2 A1 bidirectional A-port bidirectional data I/O bit 1. Logic levels referenced to VCCA. Drives up to ±24mA at 3V (±32mA at 4.5-5.5V). High-Z when DIR is high (A drives to B) is disabled - active when DIR=L (B→A).
3 A2 bidirectional A-port bidirectional data I/O bit 2. Logic levels referenced to VCCA. Drives up to ±24mA at 3V.
4 GND power_in Device ground return, 0V reference for both supplies. When either VCCA or VCCB is at GND the device enters suspend mode.
5 DIR input Direction control input, referenced to VCCA. DIR=L → B bus drives to A bus (A outputs enabled, B outputs Hi-Z); DIR=H → A drives to B (B outputs enabled, A outputs Hi-Z). Must be held at valid H/L to prevent excess ICC.
6 B2 bidirectional B-port bidirectional data I/O bit 2. Logic levels referenced to VCCB (1.65V-5.5V).
7 B1 bidirectional B-port bidirectional data I/O bit 1. Logic levels referenced to VCCB.
8 VCCB power_in B-port supply voltage rail. Recommended operating range 1.65V ≤ VCCB ≤ 5.5V. Either VCCA or VCCB may be ramped first (no sequencing required).

CAD (KiCad official)

  • Symbol: RS2T45XM
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: rs2t45xm-etched.step / rs2t45xm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs2t45xm.step / rs2t45xm.glb are the bare package body.

Provenance

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

  • Datasheet: Jiangsu RUNIC Tech datasheet (17 pp, sha256 e02b170617fa8783, retrieved 2026-08-17, tier: lcsc)
  • 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).
