IDT74LVC162245A

APPLICATIONS:

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems

DRIVE FEATURES:

• Balanced Output Drivers: ±12mA (A port)

• High Output Drivers: ±24mA (B port)

DESCRIPTION:

This 16-bit transceiver is built using advanced dual metal CMOS

technology. The LVC162245A is designed for asynchronous communica-

tion 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.
