HD74HC589 Datasheet | Hitachi Semiconductor

8-bit Serial of Parallel-input/Serial-output Shift Register (with 3-state outputs) 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 Q H) = 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:...
