Analog Devices / Maxim Integrated MAX14900E Octal High-Speed High-Side Switch

Analog Devices Inc. MAX14900E Octal High-Speed High-Side Switch is an octal power switch that features a per-channel configuration for high-side or push-pull operation. Low propagation delay, high-rate load-switching makes this device suitable for next-generation high-speed PLC systems. Each high-side switch sources 850mA continuous current with a low 165mΩ (max) on-resistance at 500mA. The ADI MAX14900E high-side switches feature 2μs (max) input-to-output propagation delay when driving resistive loads. Long cables can be driven with switching rates of up to 100kHz for PWM/PPO control in push-pull operation. Multiple high-side switches can be connected in parallel to achieve higher drive currents.
