UM3204UE

Union Semiconductor · Translators / Level Shifters · TSSOP-14

UM3204UE from Union Semiconductor, in a TSSOP-14. 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. Sets logic levels for the A-side I/Os and the OE input. Range 1.65V ≤ VCCA ≤ 3.6V, and must satisfy VCCA ≤ VCCB.
2 A1 bidirectional Channel 1 bidirectional data I/O, referenced to VCCA (low-voltage side). Placed in high-impedance state when OE is low.
3 A2 bidirectional Channel 2 bidirectional data I/O, referenced to VCCA (low-voltage side). Placed in high-impedance state when OE is low.
4 A3 bidirectional Channel 3 bidirectional data I/O, referenced to VCCA (low-voltage side). Placed in high-impedance state when OE is low.
5 A4 bidirectional Channel 4 bidirectional data I/O, referenced to VCCA (low-voltage side). Placed in high-impedance state when OE is low.
6 NC unconnected No internal connection. May be left floating or tied to any potential within absolute-maximum ratings.
7 GND power_in Ground reference for both supply rails and all I/O.
8 OE input Three-state output enable, referenced to VCCA. Pull OE low to place all A and B outputs in high-impedance (three-state) mode; drive high for normal bidirectional translation.
9 NC unconnected No internal connection. May be left floating or tied to any potential within absolute-maximum ratings.
10 B4 bidirectional Channel 4 bidirectional data I/O, referenced to VCCB (high-voltage side). Includes ±5 kV ESD protection. Placed in high-impedance state when OE is low.
11 B3 bidirectional Channel 3 bidirectional data I/O, referenced to VCCB (high-voltage side). Includes ±5 kV ESD protection. Placed in high-impedance state when OE is low.
12 B2 bidirectional Channel 2 bidirectional data I/O, referenced to VCCB (high-voltage side). Includes ±5 kV ESD protection. Placed in high-impedance state when OE is low.
13 B1 bidirectional Channel 1 bidirectional data I/O, referenced to VCCB (high-voltage side). Includes ±5 kV ESD protection. Placed in high-impedance state when OE is low.
14 VCCB power_in B-port supply voltage. Sets logic levels for the B-side I/Os. Range 2.3V ≤ VCCB ≤ 5.5V. Either VCCA or VCCB may be ramped first (no supply sequencing required).

CAD (KiCad official)

  • Symbol: UM3204UE
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: um3204ue-etched.step / um3204ue-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); um3204ue.step / um3204ue.glb are the bare package body.

Provenance

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

  • Datasheet: Union Semiconductor datasheet (17 pp, sha256 40d808e0d0a3f5e5, 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).
