Hot-selling and scarce IDT54FCT245TDB FAST CMOS OCTAL BIDIRECTIONAL TRANSCEIVERS CDIP20 spot stock

Product Descriptions

The IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology. The FCT245T/ FCT2245T, FCT640T and FCT645T are designed for asynchronous two-way communication between data buses. The transmit/receive (T/R) input determines the direction of data flow through the bidirectional transceiver. Transmit (active HIGH) enables data from A ports to B ports, and receive (active LOW) from B ports to A ports. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in HIGH Z condition.

The FCT245T/FCT2245T and FCT645T transceivers have non-inverting outputs. The FCT640T has inverting outputs.

The FCT2245T has balanced drive outputs with current limiting resistors. This offers low ground bounce, minimal undershoot and controlled output fall times- reducing the need for external series terminating resistors. The FCT2xxxT parts are plug-in replacements for FCTxxxT parts.
