DS2407
Dual Addressable Switch Plus
1-kbit Memory
www.dalsemi.com
FEATURES
Open drain PIO pins are controlled and their
logic level can be determined over 1-Wire
bus for closed-loop control
Dual Channel operation (TSOC package)
PIO pin channel. A sink capability of 50 mA
at 0.4V with soft turn-on; channel B 8 mA at
0.4V
Maximum operating voltage of 13V at PIO-
A, 6.5V at PIO–B
1024 bits user-programmable OTP EPROM
7 bytes of user-programmable status memory
to control the device
Multiple DS2407s 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 MicroLAN
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
16.3k bits/s
Low cost TO-92 or 6-pin TSOC surface
mount package
1-Wire communication operates over a wide
voltage range of 2.8V to 6.0V from -40°C to
+85°C
Supports Conditional Search with user-
programmable condition
VCC bondout for optional external supply to
the device (TSOC package only)
Hidden Mode; the device will respond only
to a Match ROM command or a Conditional
Search when in this mode.
