SGM4T245XTS16G

SGMICRO · Buffers, Drivers, Receivers, Transceivers · TSSOP-16

SGM4T245XTS16G from SGMICRO, in a TSSOP-16. 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 VCCA power_in Supply voltage VCCA, which can range from 1.2V to 5.0V; the nAn, nDIR and nOE signals are referenced to VCCA.
2 1DIR input Direction control input for the 1A/1B bus pairs: high allows transmission from nAn to nBn, low allows transmission from nBn to nAn, referenced to VCCA.
3 2DIR input Direction control input for the 2A/2B bus pairs: high allows transmission from nAn to nBn, low allows transmission from nBn to nAn, referenced to VCCA.
4 1A1 bidirectional Data input/output 1A1, referenced to VCCA.
5 1A2 bidirectional Data input/output 1A2, referenced to VCCA.
6 2A1 bidirectional Data input/output 2A1, referenced to VCCA.
7 2A2 bidirectional Data input/output 2A2, referenced to VCCA.
8 GND power_in Ground.
9 GND power_in Ground.
10 2B2 bidirectional Data input/output 2B2, referenced to VCCB.
11 2B1 bidirectional Data input/output 2B1, referenced to VCCB.
12 1B2 bidirectional Data input/output 1B2, referenced to VCCB.
13 1B1 bidirectional Data input/output 1B1, referenced to VCCB.
14 2OE input Output enable input for the 2A/2B bus pairs (active low); when high, the outputs are disabled and in high-impedance state.
15 1OE input Output enable input for the 1A/1B bus pairs (active low); when high, the outputs are disabled and in high-impedance state.
16 VCCB power_in Supply voltage VCCB, which can range from 1.2V to 5.0V; the nBn signals are referenced to VCCB.
