IDT74LVCR162245A 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE IDT74LVCR162245A 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS AND 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: This 16-bit bus transceiver is built using advanced dual metal CMOS Typical tSK(o) (Output Skew) < 250ps technology. This high-speed, low power transceiver is ideal for asynchro- ESD > 2000V per MIL-STD-883, Method 3015 > 200V using nous communication between two busses (A and B). The Direction and machine model (C = 200pF, R = 0) Output Enable controls are designed to operate this device as either two VCC = 3.3V 0.3V, Normal Range independent 8-bit transceivers or one 16-bit transceiver. The direction VCC = 2.7V to 3.6V, Extended Range control pin (DIR) controls the direction of data flow. The output enable pin CMOS power levels (0.4 W typ. static) (OE) overrides the direction control and disables both ports. All inputs are All inputs, outputs, and I/O are 5V tolerant designed with hysteresis for improved noise margin. Supports hot insertion All pins can be driven from either 3.3V or 5V devices. This feature allows Available in SSOP and TSSOP packages the use of this device as a translator in a mixed 3.3V/5V supply system. DRIVE FEATURES: The LVCR162245A has series resistors in the device output structure Balanced Output Drivers: 12mA which will significantly reduce line noise when used with light loads. The Low switching noise driver has been designed to drive 12mA at the designated threshold levels. 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 2B4 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.
