IDT74FCT163245A/C 3.3V CMOS 16-BIT BIDIRECTIONAL TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74FCT163245A/C BIDIRECTIONAL TRANSCEIVER FEATURES: DESCRIPTION: 0.5 MICRON CMOS Technology The FCT163245 16-bit transceivers are built using advanced dual Typical tSK(o) (Output Skew) < 250ps metal CMOS technology. These high-speed, low-power transceivers are ESD > 2000V per MIL-STD-883, Method 3015 > 200V using ideal for asynchronous communication between two buses (A and B). The machine model (C = 200pF, R = 0) Direction and Output Enable controls are designed to operate these devices VCC = 3.3V 0.3V, Normal Range, or VCC = 2.7V to 3.6V, Extended as either two independent 8-bit transceivers or one 16-bit transceiver. The Range direction control pin (xDIR) controls the direction of data flow. The output CMOS power levels (0.4 W typ. static) enable pin (xOE) overrides the direction control and disables both ports. Rail-to-rail output swing for increased noise margin All inputs are designed with hysteresis for improved noise margin. Low Ground Bounce (0.3V typ.) Inputs (except I/O) can be driven by 3.3V or 5V components Available in SSOP, TSSOP, and TVSOP packages FUNCTIONAL BLOCK DIAGRAM 24 1 1 DIR 2 DIR 48 25 1OE 2OE 36 47 1A1 2A1 2 13 1B1 2B1 35 46 1A2 2A2 3 14 1B2 2B2 33 44 1A3 2A3 16 5 1B3 2B3 43 32 1A4 2A4 6 17 1B4 2B4 30 41 1A5 2A5 8 19 1B5 2B5 40 29 1A6 2A6 9 20 1B6 2B6 38 27 1A7 2A7 11 22 1B7 2B7 37 26 1A8 2A8 12 23 1B8 2B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
