DESCRIPTION

This single D-type flip-flop is designed for 1.65-V to

5.5-V VCC operation.

The SN74LVC1G374 features a 3-state output

designed specifically for driving highly capacitive or

relatively low-impedance loads. This device 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 output is set to the logic level set up at the data (D)

input.

A buffered output-enable (OE) input can be used to

place the output in either a normal logic state (high or

low logic levels) or the high-impedance state. In the

high-impedance state, the output neither loads nor

drives the bus lines significantly. The high-impedance

state and increased drive provide the capability to

drive bus lines without interface or pullup

components.

OE does not affect the 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.

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.

This device is fully specified for partial-power-down

applications using Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.
