IDT74FCT3245/A 3.3V CMOS OCTAL BIDIRECTIONAL TRANSCEIVER INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS OCTAL BIDIRECTIONAL TRANSCEIVER IDT74FCT3245/A DESCRIPTION: FEATURES: The FCT3245/A octal transceivers are built using advanced dual metal CMOS technology. These high-speed, low-power transceivers are ideal for asynchronous communication between two buses (A and B). The direction control pin (DIR) controls the direction of data flow. The output enable pin (OE) overrides the direction control and disables both ports. All inputs are designed with hysteresis for improved noise margin. The FCT3245/A has series current limiting resistors. These offer low ground bounce, minimal undershoot, and controlled output fall timesreducing the need for external series terminating resistors. • 0.5 MICRON CMOS Technology • ESD > 2000V per MIL-STD-883, Method 3015; > 200V using machine model (C = 200pF, R = 0) • VCC = 3.3V ±0.3V, Normal Range • VCC = 2.7V to 3.6V, Extended Range μW typ. static) • CMOS power levels (0.4μ • Rail-to-Rail output swing for increased noise margin • Available in QSOP and TSSOP packages FUNCTIONAL BLOCK DIAGRAM DIR 1 19 A1 A2 A3 OE 2 18 B1 3 17 B2 4 16 B3 5 A4 A5 A6 15 14 A8 B5 7 13 A7 B4 6 B6 8 12 B7 11 B8 9 IDT and the IDT logo are registered trademarks of Integrated Device Technology, Inc.
