Product details

RS-232 interface in a 16-TSSOP — what you're working with

Obsolete — plan your BOM move now

If you need a pin-compatible drop-in for production continuity, the MAX3232 family has several active siblings; check the FAQ for a direct-replacement candidate.

The 250kbps data rate is the transceiver's switching ceiling — it will reliably pass 115.2 kbps UART traffic with margin, and the full-duplex architecture means you don't waste bus turnaround cycles. The 3V to 5.5V supply range lets it sit on a 3.3V logic rail without a separate level shifter, or plug straight into a legacy 5V backplane.

Package and footprint — 16-TSSOP

Housed in a 16-TSSOP (4.40 mm width) with surface-mount termination.

Frequently asked questions

What is a direct replacement for MAX3232CPWG4?

A pin-compatible alternative within the MAX3232 family is the MAX3232CDR, which shares the same 2/2 driver/receiver count, 250kbps data rate, 3V to 5.5V supply range, and 16-SOIC package (different footprint — verify your board's land pattern). For a drop-in 16-TSSOP replacement, check the active MAX3232EIPWR or MAX3232IPWR variants, which maintain the same pinout and electrical specs. Confirm the operating temperature grade against your application before substituting.

Where can I buy MAX3232CPWG4 available via RFQ confirmation?

The MAX3232CPWG4 is obsolete from the manufacturer, so standard distributor stock is depleted. Submit a request for current availability and pricing — we confirm both at quote time.

Can MAX3232CPWG4 work at 250kbps?

Yes, the MAX3232CPWG4 is rated for a data rate of 250kbps. This supports standard UART speeds like 115.2 kbps with margin, and the full-duplex operation allows simultaneous transmit and receive at that rate.
