IDT74LVC162245A 3.3V CMOS 16-BIT TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT BUS TRANSCEIVER WITH 3-STATE OUTPUTS AND 5 VOLT TOLERANT I/O IDT74LVC162245A FEATURES: DESCRIPTION: • Typical tSK(o) (Output Skew) < 250ps • 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 μ W typ. static) • CMOS power levels (0.4μ • All inputs, outputs, and I/O are 5V tolerant • Available in SSOP, TSSOP, and TVSOP packages This 16-bit transceiver is built using advanced dual metal CMOS technology. The LVC162245A is designed for asynchronous communication between data buses. The control-function implementation minimizes external timing requirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. 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. The LVC162245A has series resistors in the device output structure of the “A” port which will significantly reduce line noise when used with light loads. The driver has been designed to drive ±12mA at the designated threshold levels. The “B” port has a ±24mA driver. DRIVE FEATURES: • Balanced Output Drivers: ±12mA (A port) • High Output Drivers: ±24mA (B port) APPLICATIONS: • 5V and 3.3V mixed voltage systems • Data communication and telecommunication systems FUNCTIONAL BLOCK DIAGRAM 1DIR 24 1 2DIR 25 48 1OE 1A1 2OE 47 2A1 2 36 13 1B1 1A2 2A2 3 14 1B2 1A3 2A3 16 1B3 2B3 32 43 2A4 6 17 1B4 1A5 2B4 41 2A5 30 8 19 1B5 1A6 40 2A6 9 1A7 20 1B6 38 2A7 2B6 27 22 1B7 2B7 37 2A8 12 2B5 29 11 1A8 2B2 33 44 5 1A4 2B1 35 46 26 23 1B8 2B8 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
