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 150mA 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 common 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.
The NE/SA5090 is a high-current latched driver designed to control up to eight separate loads. It features 8 open-collector Darlington power outputs, each capable of driving a 150mA load current (up to 200mA in typical descriptions). The device operates by loading logic levels into its data input while addressing specific output lines via a 3-bit binary address.

The common clear input turns all outputs off when a logic '0' is applied.
Outputs are turned on or off by loading a logic '1' or logic '0' into the device data input.
Yes, it allows random (addressed) data entry and will operate in addressable or demultiplex mode.
