The SN74HC594DR is a 8-bit Shift Register with output register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clear inputs are provided on both the shift and storage registers. A serial output is provided for cascading purposes. The shift register clocks are positive edge triggered and shift register always is one count pulse ahead of the storage register. The parallel outputs have high-current capability.
Wide operating voltage range
High-current 3-state non-inverting outputs drive bus lines directly or up to 15 LSTTL loads
Low power consumption
15ns Typical TPD
±6mA Output drive at 5V
Independent direct overriding clears on shift registers
Green product and no Sb/Br
This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
