These hex D-type flip-flops are designed for 2.7-V
to 5.5-V V operation.

The ’LV174 are monolithic positive-edge-
triggered flip-flops with a direct clear (CLR) input.
Information at the data (D) inputs meeting the
setup time requirements is transferred to the
outputs on the positive-going edge of the clock
pulse. Clock triggering occurs at a particular
9 10 11 12 13
NC – No internal connection
voltage level and is not directly related to the transition time of the positive-going edge of the clock pulse. When
the clock (CLK) input is at either the high or low level, the D-input signal has no effect at the output.
The SN74LV174 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count
and functionality of standard small-outline packages in less than half the printed-circuit-board area.
The SN54LV174 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74LV174 is characterized for operation from –40°C to 85°C.
