digital optocoupler Broadcom ACPL-M50L-500E designed for TTL LSTTL and CMOS interface isolation
Product Overview
The ACPL-M50L, ACPL-054L, ACPL-W50L, and ACPL-K54L are low-power, low-input current, 1MBd digital optocouplers designed for electrical insulation between input and output. They utilize an insulating layer between the light-emitting diode and an integrated photon detector. Separate connections for the photodiode bias and output transistor collector enhance speed by reducing base-collector capacitance. These optocouplers offer high common-mode transient immunity (15kV/s minimum at VCM = 1500V) over a wide temperature range (-40 to 105C). Typical current transfer ratios are 140% for ACPL-M50L and 130% for ACPL-054L/W50L/K54L at IF = 3mA. They are suitable for TTL/CMOS, TTL/LSTTL, and wide bandwidth analog applications, including communications interfaces, digital signal isolation, microcontroller interfaces, and feedback elements in switching power supplies.
