74FCT245CTSOG, or “FCT245” as it is generally referred to, is an octal high-speed transceiver with non-inverting 3-state outputs manufactured by Texas Instruments. This component is part of Texas Instruments’ 74FCT line, which is a family of high performance low-power CMOS devices featuring a wide variety of logic functions and non-inverting three-state output buffers. All FCT245 devices operate from a single 2.5 V to 3.6 V power supply consuming medium to low power. This component is optimized for use with low voltage logic, and is ideal for 1.8 V, 2.5 V, and 3.3 V logic systems.

FCT245 is commonly used for high-speed data transmission applications, such as communication between microprocessors, peripheral devices, and memory systems. It is intended for both short- and long-distance point-to-point, multipoint, and bus-oriented communication between systems, and is commonly found in applications like I/O ports and memory decoders where it is used as an interface between two remote systems. The device is typically used in applications where low power dissipation and high speed data transfers are important.

The FCT245 is a low voltage octal transceiver with non-inverting three-state outputs. It consists of two independent bidirectional transceivers, each having three-state non-inverting outputs, which are disabled when the output enable (OE) input is low. The I/O levels of the FCT245 are compatible with all of the FCT logic families and TTL input logic making the FCT245 very flexible in terms of interface compatibility. The FCT245 is controlled by three signals, a data enable (DE) input, and two data inputs, each of which can be either high or low.

The data enable (DE) input, when high, allows data to be either written to or read from the device. When the DE input is low there is no effect on the device’s inputs or outputs. The two data inputs, A and B, determine the outputs of the FCT245 when the DE input is high. When A is high and B is low, the output is low; when A is low and B is high, the output is high. When both A and B are low, the output is in a high impedance state. The outputs of the FCT245 are three-state, so when the output enable (OE) input is low, the outputs are disabled and the outputs are in a high impedance state.

The FCT245 is an excellent choice for virtually any data communication requirement where medium to low power dissipation and high speed data transfers are necessary. The device’s wide array of features make it an ideal solution for signal interconnection and buffering applications in communication systems, micro-controller based equipment, high speed data processing systems, as well as in general logic designs. It is also suitable for use as a line driver or receiver in board level signal conditioning applications where low voltage operation is necessary.
