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