What this 8-bit D-type flip-flop does on the board
The SN74LVC374APWT is an 8-bit D-type flip-flop from TI's 74LVC logic family, in a 20-pin TSSOP package. It captures data on the positive edge of the clock and presents it at the outputs, with a tri-state control that lets you float the bus when the output-enable pin is high. This makes it a standard choice for registered data buses, address latches, and general-purpose storage in low-voltage digital systems.
Supply range and timing margins
The 7 ns max propagation delay at 3.3 V into a 50 pF load means the data settles well within a 100 MHz clock period, leaving margin for clock skew and trace delay. The 100 MHz clock frequency ceiling is the toggle rate of the flip-flop itself, not the bus — the actual data rate depends on the setup/hold timing of the driving and receiving devices.
The 4 pF input capacitance is low enough that the clock line sees minimal loading even with eight flip-flops on the same net.
Temperature range and where it works
The quiescent current is only 10 µA, which matters for battery-backed or always-on rails where every microamp counts.
It is sourced through authorized and independent distribution; lead time and pricing are confirmed at RFQ against the BOM quantity.
