74LVQ374 Low Voltage Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The LVQ374 is a high-speed, low-power octal D-type flipflop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flipflops.

Features
s Ideal for low power/low noise 3.3V applications s Implements patented EMI reduction circuitry s Available in SOIC JEDEC, SOIC EIAJ and QSOP packages s Guaranteed simultaneous switching noise level and dynamic threshold performance s Improved latch-up immunity s Guaranteed incident wave switching into 75 s 4 kV minimum ESD immunity s Buffered positive edge-triggered clock s 3-STATE outputs drive bus lines or buffer memory address registers
