IDT54/74FCT16245T/AT/CT/ET FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER IDT54/74FCT16245T/AT/CT/ET FEATURES: DESCRIPTION: • • • • • The FCT16245T 16-bit transceiver is built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for synchronous communication between two busses (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 FCT16245T is ideally suited for driving high-capacitance loads and lowimpedance backplanes. The output buffers are designed with power off disable capability to allow "live insertion" of boards when used as backplane drivers. • • • • 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 ≤ 1µA (max.) ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) High drive outputs (–32mA IOH, 64mA IOL) Power off disable outputs permit “live insertion” Typical VOLP (Output Ground Bounce) < 1.0V at VCC = 5V, TA = 25°C Available in the following packages: – Industrial: SSOP, TSSOP – Military: CERPACK FUNCTIONAL BLOCK DIAGRAM 1 DIR 2 DIR 1OE 2OE 1A1 2A1 1B1 2B1 1A2 2A2 1B2 2B2 1A3 2A3 1B3 2B3 1A4 2A4 1B4 2B4 1A5 2A5 1B5 2B5 1A6 2A6 1B6 2B6 1A7 2A7 1B7 2B7 1A8 2A8 1B8 2B8 IDT and the IDT logo are registered trademark of Integrated Device Technology, Inc.
