Many Options Support Broad Applications

•

The MAX14930–MAX14932 family offers all three possible

unidirectional channel configurations to accommodate

any 4-channel design; including SPI, RS-232, RS-485,

and digital I/O applications. For applications requiring

•

3 Data Rates (1Mbps, 25Mbps, 150Mbps)

3 Channel Direction Conﬁguration

2 Output Default States (High or Low)

bidirectional channels, such as I C, see the MAX14933.

3 Packages (3.8mm, 4mm, 8mm Creepage and Clearance)

Devices are available with data rates from DC up to

1Mbps, 25Mbps, or 150Mbps. Each device is also avail-

able in either a default high or default low configuration.

The default is the state an output goes to when its input

is unpowered. See the Ordering Information and Selector

Guide for the suffixes associated with each option.

●

Low Power Consumption at High Data Rates

At 1.8V:

•

2.5mA per Channel Typical at 1Mbps

5.25mA per Channel Typical at 100Mbps

At 3.3V:

•

2.6mA per Channel Typical at 1Mbps

7.1mA per Channel Typical at 100Mbps

Independent 1.71V to 5.5V supplies on each side of the

isolator also make the devices suitable for use as level

translators.

Safety Regulatory Approvals

(see Safety Regulatory Approvals)

The MAX14930–MAX14932 are available in both a 16-pin

wide body (10.3mm x 7.5mm) and narrow body (9.9mm x

3.9mm) SOIC package. The MAX14130–MAX14131 are

available in a 16-pin (6mm x 5mm) QSOP package. All

devices are rated for operation at ambient temperatures

of -40°C to +125°C.
