SN74LVC16374DGGR

Description

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, l/0 ports, bidirectional bus drivers, and working registers. It can be used as two 8-bit fip-flops or one 16-bit fip-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 outputenable (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 intermal operations of the fip-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.
