The CY54FCT373ATDMB features eight latches with 3-state outputs for bus-oriented applications. The transparent nature of the latches means that, when the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the Q outputs are latched at the levels set up at the 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 latter mode, 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 need for interface or pull-up components.

OE does not affect the internal operation of the latches or the LE. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.

The CY54FCT373ATDMB is characterized for operation from -55°C to 125°C, making it suitable for military and industrial temperature applications. The device comes in a space-saving SSOP-20 package, providing a compact solution for systems where space is at a premium.

With its fast propagation delay and low power consumption, the CY54FCT373ATDMB is an excellent choice for use in high-speed memory buffering, bus interfacing, and data storage applications where low power and high performance are required.
