NE5090 Datasheet | Philips Semiconductors

Philips Semiconductors Linear Products Product specification Addressable relay driver NE/SA5090 DESCRIPTION The NE/SA5090 addressable relay driver is a high-current latched driver, similar in function to the 9934 address decoder. The device has 8 open-collector Darlington power outputs, each capable of 150m A load current. The outputs are turned on or off by respectively loading a logic “1” or logic “0” into the device data input. The required output is defined by a 3-bit address. The device must be enabled by a CE input line which also serves the function of further address decoding. A mon clear input, CLR, turns all outputs off when a logic “0” is applied. The device is packaged in a 16-pin plastic or Cerdip package.
