DESCRIPTION:

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.

the use of this device as a translator in a mixed 3.3V/5V supply system.

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

maintaining speed performance.

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.

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

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

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

All pins can be driven from either 3.3V or 5V devices. This feature allows

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

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

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