IDT74ALVCH162245
3.3V CMOS 16-BIT BUS
TRANSCIEVER WITH
3-STATE OUTPUTS
AND BUS-HOLD
DESCRIPTION:
This 16-bit bus transceiver is built using advanced dual metal CMOS
technology. The ALVCH162245 is designed for asynchronous com-
munication between data buses. The control-function implementation
minimizes external timing requirements.
This device can be used as two 8-bit transceivers or one 16-bit
transceiver. It allows data transmission 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 that the buses are effectively isolated.
The ALVCH162245 has series resistors in the device out-put struc-
ture of the “A” port which will significantly reduce line noise when used
with light loads. This driver has been designed to drive ±12mA at the
designated threshold levels. The “B” port has a ±24mA driver.
The ALVCH162245 has “bus-hold” which retains the inputs’ last
state whenever the input bus goes to a high impedance. This prevents
floating inputs and eliminates the need for pull-up/down resistors.
APPLICATIONS:
3.3V high speed systems
3.3V and lower voltage computing systems
DRIVE FEATURES:
Balanced Output Drivers: ±12mA (A port)
High Output Drivers: ±24mA (B port)
