Product details

The National Semiconductor DS14C232CWM is a dual RS-232 transceiver integrating two drivers and two receivers in a single package.

If your board runs on 3.3 V logic, you will need a level translator or a different RS-232 transceiver rated for lower supply voltages. The 2/2 driver/receiver configuration matches the standard DB9 serial port pinout (two data lines plus handshake), so one DS14C232CWM covers a single full RS-232 port.

Lifecycle and compliance

However, the part is marked RoHS non-compliant, which is a critical constraint for BOMs destined for markets with RoHS restrictions (EU, China, California). If your assembly line or end-product requires RoHS compliance, you will need to source an exemption or select a RoHS-compliant alternate.

Frequently asked questions

Is DS14C232CWM compatible with MAX232?

The DS14C232CWM and the MAX232 are both 5 V RS-232 transceivers with 2 drivers and 2 receivers, and they share the same basic function and pinout. However, the DS14C232CWM is RoHS non-compliant, while many MAX232 variants are RoHS compliant. Verify the specific package and supply voltage requirements of your design before substituting.
