Product Description
Product Overview
The Broadcom ACPL-214 is an AC-input, single-channel, half-pitch phototransistor optocoupler. It features two inversely parallel connected light-emitting diodes optically coupled to a phototransistor, housed in a 4-pin SO package. This optocoupler offers high input-output isolation voltage of 3750 VRMS, a typical response time of 2 s, and a minimum CTR of 20% at 1 mA input current. It is suitable for I/O interfaces in programmable controllers and computers, sequence controllers, system appliances, measuring instruments, and signal transmission between circuits with different potentials and impedances.Product Attributes
