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
150 mA 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 DIP or SO package.
FEATURES
8 high-current outputs
Low-loading bus-compatible inputs
Power-on clear ensures safe operation
Will operate in addressable or demultiplex mode
Allows random (addressed) data entry
Easily expandable
Pin-compatible with 9334 (Philips or Fairchild)
