- Addressable peripheral drivers - Driver
Philips Semiconductors Linear Products Product specification Addressable peripheral drivers 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 dev
