3 / 10 page 74HC164 Document number: DS36279 Rev. 2- 2 3 of 10 www.diodes.com March 2015 © Diodes Incorporated 74HC164 400 Timing Diagram CP DSA MR Q2 Q1 unknown 13 12 15 14 9 8 11 10 5 4 7 6 1 0 3 2 DSB Q0 Q3 unknown unknown unknown Q6 Q5 unknown Q4 Q7 unknown unknown unknown Reset All Q=0 Reset All Q=0 Notes: 5. All Q values are reset to LOW when MR goes low. MR is asynchronous and overrides all other signals. 6. Serial data supplied at DSA and DSB is ANDED and transferred to Q0 on positive edge of CP. . Absolute Maximum Ratings (Note 7) (TA = +25°C, unless otherwise specified.) Symbol Description Rating Unit ESD HBM Human Body Model ESD Protection 2 kV ESD CDM Charged Device Model ESD Protection 1 kV ESD MM Machine Model ESD Protection 200 V VCC Supply Voltage Range -0.5 to +7.0 V VI Input Voltage Range (Note 8) -0.5 to +7.0 V IIK Input Clamp Current VI < -0.5V or Vi > VCC +0.5V ±20 mA IOK Output Clamp Current VO < -0.5V or VO > VCC +0.5V ±20 mA IO Continuous Output Current -0.5V < VO VCC +0.5V +/- 25 mA ICC Continuous Current through Vcc 50 mA IGND Continuous Current through GND -50 mA TJ Operating Junction Temperature -40 to +150 °C TSTG Storage Temperature -65 to +150 °C PTOT Total Power Dissipation 500 mW Notes: 7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should be within recommend values. 8. Input Voltage cannot exceed Vcc to the extent the maximum clamp current is exceeded. |
