It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. This device contains an 8-bit serial-in, parallel-out shift reg- ister that feeds an 8-bit D-type storage register. The stor- age register has eight 3-STATE outputs. Separate clocks are provided for both the shift register and the storage reg- ister. The shift register has a direct-overriding clear, serial input, and serial output (standard) pins for cascading. Both the shift register and storage register use positive-edge triggered clocks. If both clocks are connected together, the shift register state will always be one clock pulse ahead of the storage register. An input protection circuit insures that 0V to 7V can be applied to the input pins without regard to the supply volt- age. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This cir- cuit prevents device destruction due to mismatched supply and input voltages. Features s High Speed: tPD = 5.4 ns (typ) at VCC = 5V s Low power dissipation: ICC = 4 µA (max) at TA = 25°C s High noise immunity: VNIH = VNIL = 28% VCC (min) s Power down protection is provided on all inputs s Low noise: VOLP = 0.9V (typ) s Pin and function compatible with 74HC595 Ordering Code: Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
