SN74LVC16374DGGR

具有三态输出的 16 位边沿 D 类触发器 48-TSSOP -40 to 85

This 16-bit edge-triggered D-type flip-flop is designed for 2.7-V to 3.6-V VCC operation.

The SN74LVC16374 is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock CLK input, the Q outputs of the flip-flop take on the logic levels set up 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 logic levels 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 need for interface or pullup components.

OE\ does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN74LVC16374 is characterized for operation from -40°C to 85°C.
