description
This octal edge-triggered D-type flip-flop is
designed for 2.7-V to 3.6-V VCC operation.
The SN74LVC374 features 3-state outputs designed specifically for driving highly capacitive or relatively
low-impedance loads. It is particularly suitable for implementing buffer registers, input/output (I/O) ports,
bidirectional bus drivers, and working registers.
On the positive transition of the clock (CLK) input, the Q outputs are set to the logic levels at the data (D) inputs.
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high
or low) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines
significantly. The high-impedance state and the increased drive provide the capability to drive bus lines without
interface or pullup components. OE does not affect internal operations of the latch. Old data can be retained
or new data can be entered while the outputs are in the high-impedance state.
The SN74LVC374 is characterized for operation from – 40
°C to 85°C.
