TC7WBL126AFK is a low-voltage dual bus switch from Toshiba. It has a working voltage range of 2~3.6V, fast switching speed, low switching resistance, high ESD performance and on-chip power supply.
The TC7WBL126AFK is a low‑voltage dual‑bus switch IC offering two independent 2‑bit switches with separate enable signals. When the enable (OE) input is high, the corresponding switch connects port A to port B; when low, the ports are isolated.
Key specifications include an operating voltage range of 2 V to 3.6 V, a typical propagation delay of 0.31 ns at 3 V, ultra‑low ON‑resistance of about 5 Ω, and a maximum power dissipation of 200 mW. The device is supplied in an SSOP8‑P‑0.50A package and includes ESD protection on inputs.
