74LCX541MTC

onsemi · Buffers / Drivers · TSSOP-20

74LCX541MTC from onsemi, in a TSSOP-20. 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 OE1 input 3-STATE output enable input; when HIGH the O0-O3 outputs are high impedance, and OE1 should be tied to VCC through a pull-up resistor to hold the outputs in high impedance during power up or down.
2 I0 input Data input 0, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
3 I1 input Data input 1, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
4 I2 input Data input 2, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
5 I3 input Data input 3, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
6 I4 input Data input 4, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
7 I5 input Data input 5, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
8 I6 input Data input 6, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
9 I7 input Data input 7, 5V tolerant; VI may range from 0 to 5.5V, and unused inputs must be held HIGH or LOW, never left floating.
10 GND power_in Ground reference for the device.
11 O7 output 3-STATE data output 7; output drive is ±24 mA at VCC = 3.0V to 3.6V.
12 O6 output 3-STATE data output 6; output drive is ±24 mA at VCC = 3.0V to 3.6V.
13 O5 output 3-STATE data output 5; output drive is ±24 mA at VCC = 3.0V to 3.6V.
14 O4 output 3-STATE data output 4; output drive is ±24 mA at VCC = 3.0V to 3.6V.
15 O3 output 3-STATE data output 3; output drive is ±24 mA at VCC = 3.0V to 3.6V.
16 O2 output 3-STATE data output 2; output drive is ±24 mA at VCC = 3.0V to 3.6V.
17 O1 output 3-STATE data output 1; output drive is ±24 mA at VCC = 3.0V to 3.6V.
18 O0 output 3-STATE data output 0; output drive is ±24 mA at VCC = 3.0V to 3.6V.
19 OE2 input 3-STATE output enable input; when HIGH the O4-O7 outputs are high impedance, and OE2 should be tied to VCC through a pull-up resistor to hold the outputs in high impedance during power up or down.
20 VCC power_in Supply voltage, 2.0V to 3.6V operating (data retention 1.5V to 3.6V).
