DS2407

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 PIOA, 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 + 48bit 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 userprogrammable 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 w...
