IDT54/74FCT162245T/AT/CT FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER IDT54/74FCT162245T/AT/CT FEATURES: DESCRIPTION: * * * * * The FCT162245T 16-bit transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for synchronous communication between two buses (A and B). The Direction and Output Enable controls operate these devices as either two independent 8-bit transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls the direction of data flow. The output enable pin (xOE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. The FCT162245T has balanced output drive 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 FCT162245T is a plug-in replacement for the FCT16245T and ABT16245 for on-board interface applications. * * * * 0.5 MICRON CMOS Technology High-speed, low-power CMOS replacement for ABT functions Typical tSK(o) (Output Skew) < 250ps Low input and output leakage 1A (max.)
