SGM4553YN8G

SGMICRO · Translators / Level Shifters · SOT-23-8

SGM4553YN8G from SGMICRO, in a SOT-23-8. 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 VCCB power_in B ports supply voltage. Operating range 2.3V ≤ VCCB ≤ 5.5V. Sets the logic reference for the B-side I/Os. Bypass with 0.1µF close to the pin.
2 B1 bidirectional Input/Output B, channel 1. Referenced to VCCB. Bidirectional translated I/O supporting push-pull (up to 24Mbps) or open-drain (up to 2Mbps) operation.
3 B2 bidirectional Input/Output B, channel 2. Referenced to VCCB. Bidirectional translated I/O supporting push-pull (up to 24Mbps) or open-drain (up to 2Mbps) operation.
4 OE input Output Enable (active high). Referenced to VCCA. Pull OE low to place all A- and B-side outputs in 3-state (high-impedance) mode. VIH ≥ VCCA×0.8; VIL ≤ VCCA×0.25. OE has an internal pull-down and should be tied to GND through a pull-down resistor to guarantee Hi-Z during power-up/down.
5 GND power_in Ground reference for the device.
6 A2 bidirectional Input/Output A, channel 2. Referenced to VCCA. Bidirectional translated I/O supporting push-pull or open-drain operation.
7 A1 bidirectional Input/Output A, channel 1. Referenced to VCCA. Bidirectional translated I/O supporting push-pull or open-drain operation.
8 VCCA power_in A ports supply voltage. Operating range 1.65V ≤ VCCA ≤ 5.5V, with the constraint VCCA ≤ VCCB. Sets the logic reference for the A-side I/Os and OE. Bypass with 0.1µF close to the pin.
