INFORMATION
EXTENDED COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
This bus transceiver is built using advanced dual metal CMOS technol-
ogy. The LVCHR2245A device is designed for asynchronous communi-
cation between data buses. The device transmits data 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 the buses are effectively isolated.
All inputs, which are designed to sink up to 12mA, inlcude equivalent 26
resistors to reduce overshoot and undershoot.
Inputs 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 environment.
The LVCHR2245A 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.
