IDT74FCT2245AT/CT FAST CMOS OCTAL BIDIRECTIONAL TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE FAST CMOS OCTAL IDT74FCT2245AT/CT BIDIRECTIONAL TRANSCEIVER FEATURES: DESCRIPTION: A and C grades The IDT octal bidirectional transceivers are built using an advanced dual Low input and output leakage 1 A (max.) metal CMOS technology. The FCT2245T is designed for asynchronous CMOS power levels two-way communication between data buses. The transmit/receive (T/R) True TTL input and output compatibility: input determines the direction of data flow through the bidirectional trans- VOH = 3.3V (typ.) ceiver. Transmit (active high) enables data from A ports to B ports, and VOL = 0.3V (typ.) receive (active low) from B ports to A ports. The output enable (OE) input, Meets or exceeds JEDEC standard 18 specifications when high, disables both A and B ports by placing them in high Z condition. Resistor outputs -15mA IOH, 12mA IOL The FCT2245T has balanced drive outputs with current limiting resistors. Reduced system switching noise This offers low ground bounce, minimal undershoot and controlled output Available in SOIC and QSOP packages fall times- reducing the need for external series terminating resistors. The FCT2245T parts are plug-in replacements for FCT245T parts.
