IDT74LVCH162245A
DESCRIPTION:
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.
