FEATURES:

DESCRIPTION:

DRIVE FEATURES:

APPLICATIONS:

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

• High Output Drivers: ±24mA (B port)

• 5V and 3.3V mixed voltage systems

• Data communication and telecommunication systems

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

technology. This high-speed, low power transceiver is ideal for asynchro-

nous communication between two busses (A and B). The Direction and

Output Enable controls are designed to operate this device as either two

independent 8-bit transceivers or one 16-bit transceiver. The direction

control pin (DIR) controls the direction of data flow. The output enable pin

(OE) overrides the direction control and disables both ports. All inputs are

designed with hysteresis for improved noise margin.

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 LVCH162245A (B port) has been designed with a ±24mA output

driver. This driver is capable of driving a moderate to heavy load while

maintaining speed performance.

The LVCH162245 (A port) has series resistors in the device output

structure 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 LVCH162245A has “bus-hold” which retains the inputs’ last state

whenever the input goes to a high impedance. This prevents floating inputs

and eliminates the need for pull-up/down resistors.
