TC7QPB9306FT(EL)

Overview

The TC7QPB9306FT(EL) is a dual-supply bus switch manufactured by Toshiba Semiconductor and Storage. It features four independent single-pole single-throw (SPST) switches in a 14-TSSOP package. The device supports voltage levels from 1.65V to 5.5V for the A port and 2.3V to 5.5V for the B port. Key electrical parameters include a maximum on-resistance of 16 ohms, a maximum propagation delay of 2.2 ns, and a power dissipation rating of 180 mW. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-supply architecture enabling level shifting between different voltage domains
• Four independent SPST channels for flexible signal routing
• Low on-resistance for minimal signal attenuation
• High-speed switching capability with low propagation delay

Applications

• Portable equipment requiring data line protection
• Consumer products utilizing multiple voltage supplies
