DS2406
Dual Addressable Switch
Plus 1kbit Memory
www.maxim-ic.com
FEATURES
Open drain PIO pins are controlled and their
logic level can be determined over 1-Wire
bus for closed-loop control
Replaces and is fully compatible with
DS2407 but no user-programmable power-on
settings and no Hidden Mode
PIO channel A sink capability of 50mA at
0.4V with soft turn-on; channel B 8mA at
0.4V
Maximum operating voltage of 13V at
PIO-A, 6.5V at PIO-B
1024 bits user-programmable OTP EPROM
User-programmable status memory to
control the device
Multiple DS2406’s can be identified on a
common 1-Wire bus and be turned on or off
independently of other devices on the bus
Unique, factory-lasered and tested 64-bit
registration number (8-bit family code +
48-bit serial number + 8-bit CRC tester)
assures error-free selection and absolute
identity because no two parts are alike
On-chip CRC16 generator allows detection
of data transfer errors
Built-in multidrop controller ensures
compatibility with other 1-Wire net products
Reduces control, address, data, programming
and power to a single data pin
Directly connects to a single port pin of a
microprocessor and communicates at up to
16.3 kbits/s
Supports Conditional Search with user-
selectable condition
Vcc bondout for optional external supply to
the device (TSOC package only)
1-Wire communication operates over a wide
voltage range of 2.8V to 6.0V from -40°C to
+85°C
Low cost TO-92, 6-pin TSOC and Flip Chip
surface mount package
