IDT74FCT2245AT/CT FAST CMOS OCTAL BIDIRECTIONAL TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE IDT74FCT2245AT/CT FAST CMOS OCTAL BIDIRECTIONAL TRANSCEIVER FEATURES: • • • • • • • • DESCRIPTION: A and C grades Low input and output leakage ≤1μA (max.) CMOS power levels True TTL input and output compatibility: – VOH = 3.3V (typ.) – VOL = 0.3V (typ.) Meets or exceeds JEDEC standard 18 specifications Resistor outputs -15mA IOH, 12mA IOL Reduced system switching noise Available in SOIC and QSOP packages The IDT octal bidirectional transceivers are built using an advanced dual metal CMOS technology. The FCT2245T is 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 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 FCT2245T parts are plug-in replacements for FCT245T parts.
