LSF0108PW-Q100J

Nexperia · Translators, Level Shifters · TSSOP-20

LSF0108PW-Q100J from Nexperia, 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	GND	power_in	Ground (0 V) reference for the device.
2	refA	power_in	Reference voltage A, which sets the voltage level on the A-side data pins A1 to A8.
3	A1	bidirectional	Data input/output A1, the A-side end of channel 1, which is high-impedance when EN is LOW.
4	A2	bidirectional	Data input/output A2, the A-side end of channel 2, which is high-impedance when EN is LOW.
5	A3	bidirectional	Data input/output A3, the A-side end of channel 3, which is high-impedance when EN is LOW.
6	A4	bidirectional	Data input/output A4, the A-side end of channel 4, which is high-impedance when EN is LOW.
7	A5	bidirectional	Data input/output A5, the A-side end of channel 5, which is high-impedance when EN is LOW.
8	A6	bidirectional	Data input/output A6, the A-side end of channel 6, which is high-impedance when EN is LOW.
9	A7	bidirectional	Data input/output A7, the A-side end of channel 7, which is high-impedance when EN is LOW.
10	A8	bidirectional	Data input/output A8, the A-side end of channel 8, which is high-impedance when EN is LOW.
11	B8	bidirectional	Data input/output B8, the B-side end of channel 8, which is high-impedance when EN is LOW.
12	B7	bidirectional	Data input/output B7, the B-side end of channel 7, which is high-impedance when EN is LOW.
13	B6	bidirectional	Data input/output B6, the B-side end of channel 6, which is high-impedance when EN is LOW.
14	B5	bidirectional	Data input/output B5, the B-side end of channel 5, which is high-impedance when EN is LOW.
15	B4	bidirectional	Data input/output B4, the B-side end of channel 4, which is high-impedance when EN is LOW.
16	B3	bidirectional	Data input/output B3, the B-side end of channel 3, which is high-impedance when EN is LOW.
17	B2	bidirectional	Data input/output B2, the B-side end of channel 2, which is high-impedance when EN is LOW.
18	B1	bidirectional	Data input/output B1, the B-side end of channel 1, which is high-impedance when EN is LOW.
19	refB	power_in	Reference voltage B, which sets the voltage level on the B-side data pins B1 to B8.
20	EN	input	Enable input (active HIGH); when HIGH the An and Bn channels are connected (An = Bn), and when LOW they are high-impedance (Z).
