Addressable peripheral drivers

853-0951 13721

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

device is packaged in an 18-pin plastic or Cerdip package.
