description
NC – No internal connection
The ’LV175A devices are quadruple D-type
flip-flops designed for 2-V to 5.5-V V operation.
CC
These devices have a direct clear (CLR) input and feature complementary outputs from each flip-flop.
Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the
positive-going edge of the clock (CLK) pulse.
Clock triggering occurs at a particular voltage level and is not directly related to the transition time of the
positive-going edge of CLK. When CLK is at either the high or low level, the D input has no effect at the output.
The SN54LV175A is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74LV175A is characterized for operation from –40°C to 85°C.
