FSA4157P6X

onsemi · Analog Switches, Multiplexers · SC-70-6(SOT-363)

FSA4157P6X from onsemi, in a SC-70-6(SOT-363). 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 B1 passive Analog switch data port B1. Connected to common port A when the control input S is HIGH. Bidirectional signal path with ~1.15 Ω max Ron at 4.5 V VCC; signal voltage must remain within 0 V to VCC.
2 GND power_in Device ground reference (0 V).
3 B0 passive Analog switch data port B0. Connected to common port A when the control input S is LOW. Bidirectional analog signal path with ~1.15 Ω max Ron at 4.5 V VCC; signal voltage must remain within 0 V to VCC.
4 A passive Common analog switch data port A. Routed to B0 (S = LOW) or B1 (S = HIGH) via break-before-make action. Bidirectional; signal voltage must remain within 0 V to VCC.
5 VCC power_in Positive supply. Operating range 1.65 V to 5.5 V (FSA4157) or 2.7 V to 5.5 V (FSA4157A). Absolute maximum −0.5 V to +6.0 V. Typical ICC ≈ 0.1 µA.
6 S input TTL-compatible select input. LOW connects B0↔A; HIGH connects B1↔A. Must be driven HIGH or LOW at all times (must not float). Over-voltage tolerant control circuitry; VIH ≥ 2.0 V (VCC = 2.7-3.6 V) or ≥ 2.4 V (4.5-5.5 V).

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: onsemi datasheet (14 pp, sha256 c76205c0678a3f86, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
