74LVX174 Low Voltage Hex D-Type Flip-Flop with Master Reset
May 1993 Revised March 1999
74LVX174 Low Voltage Hex D-Type Flip-Flop with Master Reset
General Description
The LVX174 is a high-speed hex D flip-flop. The device is used primarily as a 6-bit edge-triggered storage register. The information on the D inputs is transferred to storage during the LOW-to-HIGH clock transition. The device has a Master Reset to simultaneously clear all flip-flops.
Features
s Input voltage level translation from 5V to 3V s Ideal for low power/low noise 3.3V applications s Guaranteed simultaneous switching noise level and dynamic threshold performance

Absolute Maximum Ratings(Note 1)
Supply Voltage (VCC) DC Input Diode Current (IIK) VI = -0.5V DC Input Voltage (VI) DC Output Diode Current (IOK) VO = -0.5V VO = VCC + 0.5V DC Output Voltage (VO) DC Output Source or Sink Current (IO) DC VCC or Ground Current (ICC or IGND) Storage Temperature (TSTG) Power Dissipation (PD) ±50 mA -65°C to +150°C 180 mW ±25 mA -20 mA +20 mA -0.5V to VCC + 0.5V -20 mA -0.5V to 7V -0.5V to +7.0V
Recommended Operating Conditions (Note 2)
Supply Voltage (VCC) Input Voltage (VI) Output Voltage (VO) Operating Temperature (TA) Input Rise and Fall Time (t/V) 2.0V to 3.6V 0V to 5.5V 0V to VCC -40°C to +85°C 0 ns/V to 100 ns/V
Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: Unused inputs must be held HIGH or LOW. They may not float.
