3.3V CMOS 16-BIT INVERTING

BUFFER/LINE DRIVER

WITH 3-STATE OUTPUTS

AND BUS-HOLD

FEATURES:

DESCRIPTION:

• 0.5 MICRON CMOS Technology

This 16-bit inverting buffer/line driver is built using advanced dual metal

CMOStechnology.TheALVCH16540offersbus/backplaneinterfacecapabil-

itywithimprovedpackingdensityandaflow-throughorganizationforsimplifying

boardlayout.Itisdesignedspecificallytoimprovetheperformanceanddensity

andtransmitters.Thethree-statecontrolsoperatethisdeviceinaquad-nibble,

dual-byte,orsingle16-bitwordmode.The3-stateoutputsarecontrolledbythe

output enable (OE) pins. A high on OE causes the outputs to force a high

impedanceoff-state.Allinputsaredesignedwithhysteresisforimprovednoise

margin.

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

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

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

• 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

The ALVCH16540 has been designed with a ±24mA output driver. This

driveriscapableofdrivingamoderatetoheavyloadwhilemaintainingspeed

performance.

The ALVCH16540 has “bus-hold” which retains the inputs’ last state

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for heavy loads

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
