RS-232 transceiver for mixed-voltage serial links
Data rate is rated at 250 kbps, which covers typical RS-232 applications like industrial terminal links, point-of-sale equipment, and legacy peripheral interfaces. The receiver hysteresis of 300 mV provides noise immunity on long cable runs.
Supply range and temperature grade
The wide supply range (2.4 V to 5.5 V) allows direct connection to common logic rails without an external regulator. Package is 20-TSSOP (4.40 mm width) with surface-mount footprint. The tape-and-reel option (MAX3381ECUP+T) is the standard ordering code for automated assembly; cut-tape also available for prototyping.
Lifecycle and sourcing posture
ROHS3 compliant. This is a current-production part — no last-time-buy pressure, no allocation risk reported across distribution channels. For BOM planning: the part is widely available through multiple distributor channels. No direct replacement or pin-compatible second source is listed by the manufacturer; the MAX3381E family shares the same base function but verify the package and supply range against your board.
