Product specification
NE590/591
DESCRIPTION
The NE590/591 addressable peripheral drivers are high current
latched drivers, similar in function to the 9334 address decoder. The
device has eight Darlington power outputs, each capable of 250mA
load current. The outputs are turned on or off by respectively loading
a logic high or logic low 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. A common clear input, CLR, turns all outputs off
when a logic low is applied.
The NE590 has eight open-collector Darlington outputs which sink
current to ground. The device is packaged in a 16-pin plastic or
Cerdip package.
The NE591 has eight open-emitter Darlington outputs which source
current to an external load from a common collector line, VS. This
VS line need not necessarily be the same as the 5V VCC supply. The
device is packaged in an 18-pin plastic or Cerdip package.
