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 commu-
nication between data buses. The control-function implementation mini-
mizes 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 structure
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 .EATURES:
Balanced Output Drivers: ±12mA (A port)
