Product Overview
Maxim MAX3226ECAE: one RS-232 driver and one receiver in a 16-pin SSOP, running from a 3.0V to 5.5V supply with ±15kV ESD protection and AutoShutdown Plus. This is the original leaded version, not the lead-free MAX3226ECAE+. Maxim is now part of Analog Devices.
Key Features
- One driver, one receiver (1/1)
- 250kbps guaranteed data rate
- ESD protection: ±15kV Human Body Model, ±8kV IEC 1000-4-2 contact discharge, ±15kV IEC 1000-4-2 air-gap discharge
- Supply: 3.0V to 5.5V
- 1uA supply current in AutoShutdown Plus
- READY output
- Commercial temperature range: 0°C to +70°C
- 16-pin SSOP surface-mount package, leaded (non-RoHS) version
Applications
- Adding a TX/RX serial console header to a 3.3V or 5V microcontroller board
- Replacing a failed MAX3226ECAE on a board built around the leaded original
- Battery-powered loggers and field instruments whose serial port sits idle most of the day, where AutoShutdown Plus drops supply current to 1uA
Frequently Asked Questions
Does it work from a 3.3V supply?
Yes. It runs from 3.0V to 5.5V, so a 3.3V or a 5V rail both work.
Is this the lead-free MAX3226ECAE+?
No. It is the original leaded MAX3226ECAE, marked MAX3226E over CAE, and it is not RoHS compliant.
Will it carry a 115.2k baud link?
Yes. It is guaranteed to 250kbps, which covers 115.2k and 230.4k baud.
A serial header is where a charged cable or a stray fingertip lands first, and this is the chip that sits right behind it. Lay it out close to the connector and keep the traces short.
