MAX3378EEUD+T

Maxim Integrated · Translators / Level Shifters · TSSOP-14

MAX3378EEUD+T from Maxim Integrated, in a TSSOP-14. 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 VL power_in Logic input voltage, with +1.2V ≤ VL ≤ (VCC + 0.3V).
2 I/O VL1 bidirectional Input/output 1, referenced to VL.
3 I/O VL2 bidirectional Input/output 2, referenced to VL.
4 I/O VL3 bidirectional Input/output 3, referenced to VL.
5 I/O VL4 bidirectional Input/output 4, referenced to VL.
6 N.C. unconnected No connection; not internally connected.
7 GND power_in Ground.
8 THREE-STATE input Three-state output mode enable; pulling it low places the device in three-state output mode, where I/O VCC_ and I/O VL_ are high impedance, and logic is referenced to VL.
9 N.C. unconnected No connection; not internally connected.
10 I/O VCC4 bidirectional Input/output 4, referenced to VCC.
11 I/O VCC3 bidirectional Input/output 3, referenced to VCC.
12 I/O VCC2 bidirectional Input/output 2, referenced to VCC.
13 I/O VCC1 bidirectional Input/output 1, referenced to VCC.
14 VCC power_in Input voltage, with +1.65V ≤ VCC ≤ +5.5V.
