The VHC595 is an advanced high-speed CMOS Shift Registerfabricated with silicon gate CMOS technology. Itachieves the high-speed operation similar to equivalentBipolar Schottky TTL while maintaining the CMOS lowpower dissipation.
This device contains an 8-bit serial-in, parallel-out shift registerthat feeds an 8-bit D-type storage register. The storageregister has eight 3-STATE outputs. Separate clocksare provided for both the shift register and the storage register.
The shift register has a direct-overriding clear, serialinput, and serial output (standard) pins for cascading. Boththe shift register and storage register use positive-edgetriggered clocks. If both clocks are connected together, theshift register state will always be one clock pulse ahead ofthe storage register.
An input protection circuit insures that 0V to 7V can beapplied to the input pins without regard to the supply voltage.This device can be used to interface 5V to 3V systemsand two supply systems such as battery backup. This circuitprevents device destruction due to mismatched supplyand input voltages.
■ High Speed: tPD = 5.4 ns (typ) at VCC = 5V
■ Low power dissipation: ICC = 4 µA (max) at TA = 25°C
■ High noise immunity: VNIH = VNIL = 28% VCC (min)
■ Power down protection is provided on all inputs
■ Low noise: VOLP = 0.9V (typ)
■ Pin and function compatible with 74HC595
