TC7W66FK

TOSHIBA LF T · Signal Switches / Encoders & Decoders / Multiplexers · VSSOP-8-0.5mm

TC7W66FK from TOSHIBA LF T, in a VSSOP-8-0.5mm. 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 IN/OUT 1 bidirectional Bilateral analog/digital switch terminal 1A of switch 1. Signal may flow in either direction between this pin and pin 2 when CONT 1 is high. Signal range 0 to VCC.
2 OUT/IN 1 bidirectional Bilateral analog/digital switch terminal 1B of switch 1. Signal may flow in either direction between this pin and pin 1 when CONT 1 is high. Signal range 0 to VCC.
3 CONT 2 input Control input for switch 2. Switch is ON when C is high (VIHC ≥ 0.7·VCC typ.), OFF when low. Input range 0 to VCC; high-impedance CMOS input with ESD protection.
4 GND power_in Ground reference (0 V) for the device and lower rail for switched signals.
5 IN/OUT 2 bidirectional Bilateral analog/digital switch terminal 2A of switch 2. Signal may flow in either direction between this pin and pin 6 when CONT 2 is high. Signal range 0 to VCC.
6 OUT/IN 2 bidirectional Bilateral analog/digital switch terminal 2B of switch 2. Signal may flow in either direction between this pin and pin 5 when CONT 2 is high. Signal range 0 to VCC.
7 CONT 1 input Control input for switch 1. Switch is ON when C is high (VIHC ≥ 0.7·VCC typ.), OFF when low. Input range 0 to VCC; high-impedance CMOS input with ESD protection.
8 VCC power_in Positive supply voltage, 2 V to 12 V (operating). Absolute maximum -0.5 V to 13 V. Sets the upper rail for both control and switched signal voltages. Bypass with a local ceramic capacitor.

Provenance

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

  • Datasheet: TOSHIBA LF T datasheet (9 pp, sha256 115a09cc5511b147, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
