Push-pull outputs on both reset pins mean no external pull-up resistor is needed — the outputs drive directly to the supply rail or ground, saving a passive component on the board. ## Threshold and timing — what they mean for the BOM With a 4.625V threshold, this part is designed to supervise a nominal 5V supply rail, asserting reset when the rail drops to roughly 92.5% of nominal — a typical margin for TTL or 5V CMOS logic before data corruption. The 140ms minimum timeout is long enough to ride through most power-supply turn-on transients and hot-plug events, but short enough that a 5V microcontroller with a fast oscillator does not stall through a legitimate power cycle. Surface-mount only — the tape-and-reel or cut-tape packaging options suit both prototype assembly and production pick-and-place without a separate reel change. ROHS3 compliant, with no restricted substances per EU directive — the part clears global BOM compliance requirements without a waiver or exemption.","metaTitle":"DS1814BR-5+T&R Analog Devices Supervisor IC","metaDescription":"DS1814BR-5+T&R Analog Devices MicroMonitor simple reset/power-on reset IC.
