Product specification
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
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.
