IDT74LVCH32245A
DESCRIPTION:
This 32-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 the device as either four
independent 8-bit transceivers or one 32-bit transceiver. The direction
control pins (DIR) control the direction of data flow. The output enable pins
(OE) override the direction control and disable both ports. All inputs are
designed with hysteresis for improved noise margin.
All pins can be driven fromeither 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mxed 3.3V/5V supply system
The LVCH32245A has been designed with a
±
24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining
speed performance
The LVCH32245A has “bus-hold” which retains the inputs’ last state
whenever the input goes to a high impedance. This prevents floating inputs
and elimnates the need for pull-up/down resistors.
