74LVC374A

OCTAL D-TYPE FLIP-FLOP WITH 3 STATE OUTPUTS

Description

Pin Assignments

The 74LVC374A provides eight edge-triggered D-type flip-flops

featuring 3-state outputs designed specifically for driving highly

capacitive or relatively low-impedance loads. These devices are

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 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 the high-impedance state. In the

high-impedance state, the outputs neither load nor drive 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 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.
