Description
The HD74HC589 is similar in function to the HD74HC597, which is not a 3-state device.
This device consists of an 8-bit storage latch which feeds parallel data to an 8-bit shift register. Data can also be loaded
serially (see Function Table). The shift register output, OH, is a three-state output, allowing this device to be used in
bus-oriented systems.
Features
• High Speed Operation: tpd (Shift Clock to QH) = 15 ns typ (CL = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
