Technical Specifications

The DG271CJ operates with a supply voltage range of ±4.5 V to ±18 V and features TTL and CMOS compatible logic inputs, simplifying its integration with digital control systems. It offers low on-resistance of typically 15 Ω, minimizing signal loss and distortion during switching. The fast switching speed, with tON = 150 ns and tOFF = 100 ns, makes it suitable for high-frequency applications. Its break-before-make switching action ensures that one channel is fully turned off before the other is turned on, preventing signal contention.
