BL1551B Description

Short technical summary and product information.

The BL1551B from Shanghai Belling Co., Ltd. is a single-pole double-throw (SPDT) analog switch designed for a wide range of applications. It features a high bandwidth of 350MHz, making it suitable for high-frequency signal routing.

 

Key electrical characteristics include a typical on-resistance of 2.7Ω at 5.0V and a wide power supply range from 1.8V to 5.5V. The switch also boasts fast switching times with ton at 25ns and toff at 17ns, along with high off-isolation of 84dB at 1MHz.

 

This analog switch operates within a temperature range of -40℃ to 125℃ and supports rail-to-rail signal range. It is compatible with TTL/CMOS logic levels and features a break-before-make switching function to prevent signal disruption.

 

The BL1551B is supplied in a compact SC70-6 package, suitable for portable electronic devices and other space-constrained applications. Its applications include wireless handsets, MP3 players, PDAs, and audio/video signal routing.
