3.3V CMOS 16-BIT BUS

IDT74ALVCH162245

TRANSCIEVER WITH

3-STATE OUTPUTS

AND BUS-HOLD

ꢀEATURES:

• 0.5 MICRON CMOS Technology

• Typical tSK(o) (Output Skew) < 250ps

• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using

machine model (C = 200pF, R = 0)

DESCRIPTION:

This 16-bitbus transceiveris builtusingadvanceddualmetalCMOS

technology.The ALVCH162245is designedforasynchronous commu-

nicationbetweendatabuses.Thecontrol-functionimplementationmini-

mizesexternaltimingrequirements.

• VCC = 3.3V ± 0.3V, Normal Range

• VCC = 2.7V to 3.6V, Extended Range

• VCC = 2.5V ± 0.2V

• CMOS power levels (0.4µ W typ. static)

• Rail-to-Rail output swing for increased noise margin

• Available in SSOP, TSSOP, and TVSOP packages

This device can be used as two 8-bit transceivers or one 16-bit

transceiver.ItallowsdatatransmissionfromtheAbustotheBbusorfrom

theBbustotheAbus,dependingonthelogiclevelatthedirection-control

(DIR) input. The output-enable (OE) input can be used to disable the

device sothatthe buses are effectivelyisolated.

TheALVCH162245has series resistors inthedeviceout-putstructure

ofthe“A”portwhichwillsignificantlyreducelinenoisewhenusedwithlight

loads. This driverhas been designedtodrive ±12mAatthe designated

threshold levels. The “B” port has a ±24mA driver.

DRIVE ꢀEATURES:

• Balanced Output Drivers: ±12mA (A port)

• High Output Drivers: ±24mA (B port)

The ALVCH162245has “bus-hold”whichretains the inputs’laststate

whenevertheinputbus goes toahighimpedance.This prevents floating

inputs andeliminates the needforpull-up/downresistors.

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
