Product Description

The SN74LC374A contains eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The flip-flops are designed to store data entered on the D inputs when the clock (CLK) input is on a rising edge. Additionally, a clear (CLR) input is provided to directly clear each flip-flop synchronously with the clock.

One of the distinctive features of the SN74LC374A is its 3-state outputs, which allow the device to be used in bus-oriented applications. The outputs can be put in a high impedance state, effectively disconnecting the flip-flop from the bus. This is achieved through the use of an Output Enable (OE) input, which, when high, disables the outputs by placing them in a high impedance state.

Constructed with Texas Instruments' advanced technology, the SN74LC374A provides a significant reduction in power consumption without sacrificing speed. This makes it an ideal choice for interfacing with high-speed microprocessors, and it is widely used in memory address latches, data storage, and data transferring systems.

Overall, the SN74LC374A offers a combination of high-speed operation, low power consumption, and the versatility needed for modern digital systems. It is available in a variety of packages to suit different application requirements and design preferences.
