3.3V CMOS 16-BIT BUS
TRANSCEIVER WITH
3-STATE OUTPUTS
AND BUS-HOLD
DESCRIPTION:
This 16-bit bus transceiver is built using advanced dual metal CMOS
technology.TheALVCH16245isdesignedforasynchronouscommunication
betweendatabuses.Thecontrol-functionimplementationminimizesexternal
timingrequirements.
Thisdevicecanbeusedastwo8-bittransceiversorone16-bittransceiver.
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)inputcanbeusedtodisablethedevicesothatthebuses
are effectively isolated.
The ALVCH16245 has been designed with a ±24mA output driver. This
driver is capable of driving a moderate to heavy load while maintaining speed
performance.
The ALVCH16245 has “bus-hold” which retains the inputs’ last state
whenevertheinputbusgoestoahighimpedance.Thispreventsfloatinginputs
and eliminates the need for pull-up/down resistors.
APPLICATIONS:
3.3V high speed systems
3.3V and lower voltage computing systems
DRIVE FEATURES:
High Output Drivers: ±24mA
Suitable for heavy loads
