DS2406：Dual Addressable Switch Plus 1Kb Memory

The DS2406 Dual Addressable Switch Plus Memory offers a simple way to remotely control a pair of open drain transistors and to monitor the logic level at each transistor's output via the 1-Wire® bus for closed loop control. Each DS2406 has its own 64-bit ROM registration number that is factory lasered into the chip to provide a guaranteed unique identity for absolute traceability. The device's 1024 bits of EPROM can be used as electronic label to store information such as switch function, physical location, and installation date. Communication with the DS2406 follows the standard Dallas Semiconductor 1-Wire protocol and can be accomplished with minimal hardware such as a single port pin of a microcontroller. Multiple DS2406 devices can reside on a common 1-Wire network and be operated independently of each other. Individual devices will respond to a Conditional Search command if they qualify for certain user-specified conditions, which include the state of the output transistor, the static logic level or a voltage transition at the transistor's output.

Key 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
