Product details

At 120 kbps the ADM232LARZ is a solid fit for legacy RS-232 links running 9600 baud to 115200 baud — the common range for industrial terminals, PLC programming ports, and serial console cables. If your design targets 230 kbps or higher (e.g., faster firmware uploads or multi-drop polling), the ADM232AARNZ sibling is rated for 200 kbps and shares the same pinout and package.

Package and footprint — 16-SOIC wide-body

Housed in a 16-SOIC wide-body (0.295-inch body width, 7.50 mm), the ADM232LARZ uses the standard SOIC-16W land pattern. No exposed pad — thermal dissipation is through the leads and board copper. The wide-body footprint is common across the ADM232 family, so a layout done for the ADM232LARZ also accepts the ADM232LJRZ or ADM232AARNZ without a board spin.

Lifecycle — active, no phase-out risk

ROHS3 compliant.

Frequently asked questions

What is the data rate of ADM232LARZ?

The ADM232LARZ is rated for a maximum data rate of 120 kbps.

Is ADM232LARZ compatible with 3.3V logic?

Interfacing with a 3.3 V UART needs external level translation or a 5 V-tolerant I/O pin.

What is a direct equivalent for ADM232LARZ?

The ADM232LJRZ is a drop-in replacement with the same pinout, package, and 120 kbps data rate, but its temperature range is limited to 0°C to 70°C — not suitable for industrial environments. The ADM232AARNZ also fits the same footprint and runs at 200 kbps with 400 mV hysteresis.
