Functional Description

The CY54FCT244CTDMB is an octal buffer and line driver with 3-state outputs. It is designed to drive bus transceivers, line drivers, or high-capacitance loads. The CY54FCT244CTDMB has eight input buffers (A0-A7) and eight output buffers (Y0-Y7). The input buffers are connected to the output buffers through a set of eight 2:1 multiplexers. The select inputs (S0 and S1) are used to select which of the two inputs (A or B) is connected to the output buffer.

The CY54FCT244CTDMB also has three enable inputs (E1-E3). When all three enable inputs are high, the output buffers are enabled and the outputs follow the state of the inputs. When any of the enable inputs are low, the output buffers are disabled and the outputs are in the high-impedance state.

The CY54FCT244CTDMB is a high-performance CMOS device that is designed for operation in a variety of applications. It features high-drive outputs, a wide operating voltage range, low power consumption, and fast propagation delays.
