IDT74LVC16245A 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVC16245A BUS TRANSCEIVER WITH 3-STATE OUTPUTS, 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: Typical tSK(o) (Output Skew) < 250ps This 16-bit bus transceiver is built using advanced dual metal CMOS ESD > 2000V per MIL-STD-883, Method 3015 > 200V using technology. This high-speed, low power transceiver is ideal for asynchro- machine model (C = 200pF, R = 0) nous communication between two busses (A and B). The Direction and VCC = 3.3V 0.3V, Normal Range Output Enable controls are designed to operate this device as either two VCC = 2.7V to 3.6V, Extended Range independent 8-bit transceivers or one 16-bit transceiver. The direction CMOS power levels (0.4 W typ. static) control pin (DIR) controls the direction of data flow. The output enable pin All inputs, outputs, and I/O are 5V tolerant (OE) overrides the direction control and disables both ports. All inputs are Supports hot insertion designed with hysteresis for improved noise margin. Available in SSOP and TSSOP packages All pins can be driven from either 3.3V or 5V devices. This feature allows the use of this device as a translator in a mixed 3.3V/5V supply system. DRIVE FEATURES: The LVC16245A has been designed with a 24mA output driver. This High Output Drivers: 24mA driver is capable of driving a moderate to heavy load while maintaining Reduced system switching noise speed performance. APPLICATIONS: 5V and 3.3V mixed voltage systems Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 24 1 1DIR 2DIR 25 48 1OE 2OE 36 47 1A1 2A1 2 13 1B1 2B1 46 35 1A2 2A2 3 14 1B2 2B2 33 44 1A3 2A3 16 5 1B3 2B3 32 43 1A4 2A4 6 17 1B4 B4 2 41 30 1A5 2A5 8 19 1B5 2B5 40 29 1A6 2A6 9 20 1B6 2B6 38 27 1A7 2A7 11 22 1B7 2B7 26 37 1A8 2A8 23 12 1B8 2B8 IDT and the IDT logo is a registered trademark of Integrated Device Technology, Inc.
