It achieves the high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissi- pation. The VHC164 is a high-speed 8-Bit Serial-In/Paral- lel-Out Shift Register. Serial data is entered through a 2- input AND gate synchronous with the LOW-to-HIGH transi- tion of the clock. The device features an asynchronous Master Reset which clears the register, setting all outputs LOW independent of the clock. An input protection circuit insures that 0V to 7V can be applied to the input pins with- out regard to the supply voltage. This device can be used to interface 5V to 3V systems and two supply systems such as battery backup. This circuit prevents device destruction due to mismatched supply and input voltages. Features s High Speed: fMAX = 175 MHz 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 provided on all inputs s Low noise: VOLP = 0.8V (max) s Pin and function compatible with 74HC164 Ordering Code: Surface mount packages are also available on Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
