IDT54/74FCT162245T/AT/CT FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT IDT54/74FCT162245T/AT/CT BIDIRECTIONAL TRANSCEIVER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT162245T 16-bit transceiver is built using advanced dual metal High-speed, low-power CMOS replacement for ABT functions CMOS technology. These high-speed, low-power transceivers are ideal for Typical tSK(o) (Output Skew) < 250ps synchronous communication between two buses (A and B). The Direction and Low input and output leakage 1A (max.) Output Enable controls operate these devices as either two independent 8-bit ESD > 2000V per MIL-STD-883, Method 3015 > 200V using transceivers or one 16-bit transceiver. The direction control pin (xDIR) controls machine model (C = 200pF, R = 0) the direction of data flow. The output enable pin (xOE) overrides the direction Balanced Output Drivers: control and disables both ports. All inputs are designed with hysteresis for 24mA (industrial) improved noise margin. 16mA (military) The FCT162245T has balanced output drive with current limiting resistors. Reduced system switching noise This offers low ground bounce, minimal undershoot, and controlled output fall Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V, timesreducing the need for external series terminating resistors. The TA = 25C FCT162245T is a plug-in replacement for the FCT16245T and ABT16245 for Available in the following packages: on-board interface applications.
