Product details

RS-232 transceiver with 3 drivers, 5 receivers

The 500 mV receiver hysteresis provides noise margin for RS-232 links running over longer cables or in electrically noisy environments, reducing the risk of bit errors from coupled interference.

Commercial temperature range and surface-mount footprint

The 20-SSOP (0.209", 5.30mm width) package uses a surface-mount footprint with 0.65 mm pitch, which routes easily on a two-layer board for most RS-232 port applications.

Frequently asked questions

What is the difference between SN75185DB and SN75185D?

The SN75185DB uses a 20-SSOP package (0.209", 5.30mm width), while the SN75185D uses a 20-SOIC body. Both share the same 3/5 driver/receiver count, 4.5V–5.5V supply, and 500 mV hysteresis; the package difference affects board footprint and thermal dissipation.

Is SN75185DB RoHS compliant?

Yes, the SN75185DB is ROHS3 compliant per the lifecycle record.
