DESCRIPTION The 74VHC594 is an high speed CMOS 8-BIT SHIFT REGISTERS fabricated with sub-micron silicon gate C2MOS technology. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Separate clocks and direct overriding clear (SCLR, RCLR) are provided for both the shift register and the storage register. SOP TSSOP Table 1: Order Codes PACKAGE T&R SOP TSSOP M74VHC594RMTR M74VHC594TTR A serial (QH’) output is provided for cascading purposes. Both the shift register and storage register use positive-edge triggered clocks. If the clocks are connected together, the shift register state will always be one clock pulse ahead of the storage register. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
