DESCRIPTION
The 74LV174 is a low–voltage Si–gate CMOS device and is pin and
function compatible with the 74HC/HCT174.
The 74LV174 has six edge–triggered D–type flip–flops with
individual D inputs and Q outputs. The common clock (CP) and
master reset (MR) inputs load and reset (clear) all flip–flops
simultaneously.
The register is fully edge–triggered. The state of each D input, one
set–up time prior to the LOW–to–HIGH clock transition, is
transferred to the corresponding output of the flip–flop.
A LOW level on the MR input forces all outputs LOW, independently
of clock or data inputs.
The device is useful for applications requiring true outputs only and
clock and master reset inputs that are common to all storage
elements.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
DC CHARACTERISTICS FOR THE LV FAMILY
Over recommended operating conditions voltages are referenced to GND (ground = 0V)
