Product details

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.

Frequently asked questions

Does MAX3381ECUP+T replace MAX3381E?

The MAX3381E family shares the same RS-232 transceiver function and 2/2 driver/receiver count, but package and supply range may differ. Verify the pinout and voltage rating against your BOM before substitution — the manufacturer does not list a direct cross-reference.

What is the operating temperature of MAX3381ECUP+T?

Not rated for industrial or automotive ambient conditions.

Can MAX3381ECUP+T be used with 3.3V?

Yes, the supply range is 2.4 V to 5.5 V, so 3.3 V is within specification. The transceiver will operate at full performance at 3.3 V.

What is the data rate of MAX3381ECUP+T?

250 kbps, which is typical for RS-232 applications. For higher-speed serial links (e.g., 1 Mbps), consider a different transceiver family.
