IDT74LVC162245A 3.3V CMOS 16-BIT TRANSCEIVER WITH 3-STATE OUTPUTS INDUSTRIAL TEMPERATURE RANGE 3.3V CMOS 16-BIT IDT74LVC162245A BUS TRANSCEIVER WITH 3-STATE OUTPUTS AND 5 VOLT TOLERANT I/O DESCRIPTION: FEATURES: Typical tSK(o) (Output Skew) < 250ps This 16-bit transceiver is built using advanced dual metal CMOS ESD > 2000V per MIL-STD-883, Method 3015 > 200V using technology. The LVC162245A is designed for asynchronous communica- machine model (C = 200pF, R = 0) tion between data buses. The control-function implementation minimizes VCC = 3.3V 0.3V, Normal Range external timing requirements. This device can be used as two 8-bit VCC = 2.7V to 3.6V, Extended Range transceivers or one 16-bit transceiver. It allows data transmission from the CMOS power levels (0.4 W typ. static) A bus to the B bus or from the B bus to the A bus, depending on the logic All inputs, outputs, and I/O are 5V tolerant level at the direction-control (DIR) input. The output-enable (OE) input can Available in SSOP and TSSOP packages 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 DRIVE FEATURES: resistor is determined by the current-sinking capability of the driver. Balanced Output Drivers: 12mA (A port) All pins can be driven from either 3.3V or 5V devices. This feature allows High Output Drivers: 24mA (B port) 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 APPLICATIONS: the A port which will significantly reduce line noise when used with light 5V and 3.3V mixed voltage systems loads. The driver has been designed to drive 12mA at the designated Data communication and telecommunication systems threshold levels. The B port has a 24mA driver.
