The reset output is open-drain, so it can be pulled up to a different logic rail than the monitored voltage, and the reset timeout is adjustable via an external capacitor, giving the downstream processor time to stabilize after power-up. Housed in a 5-pin SOT-23-5 (SC-74A) package, it shares the same footprint as many other small supervisors — the pinout is standard enough that a board layout can often accommodate a second-source candidate without a respin. ## Active production and compliance Sourced to order through independent distribution; availability and current pricing confirmed at RFQ.","metaTitle":"MAX6420UK33+T Multi-Voltage Supervisor, 3.3V, SOT-23-5","metaDescription":"MAX6420UK33+T multi-voltage supervisor from Analog Devices.
