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, 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.
