BUS-INTERFACE D-TYPE

LATCH WITH 3-STATE OUT-

PUTS AND BUS-HOLD

FEATURES:

DESCRIPTION:

• 0.5 MICRON CMOS Technology

The ALVCH16843 is built using advanced dual metal CMOS technology.

Thisdevicehastwo9-bitD-typelatchesfeaturingseparateD-typeinputsfor

eachlatchand3-stateoutputsforbusorientedapplications.Thetwosections

of each register are controlled independently by the latch enable (LE), clear

(CLR), preset (PRE) and output enable (OE) control pins.

• 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

When OE is low, the data in the registers appear at the outputs. When OE

is high, the outputs are in the high impedance OFF state. Operation of the OE

input does not affect the state of the flip-flops.

The ALVCH16843 has been designed with a ±24mA output driver. This

driveriscapableofdrivingamoderatetoheavyloadwhilemaintainingspeed

performance.

The ALVCH16843 has “bus-hold” which retains the inputs’ last state

whenevertheinputbusgoestoahighimpedance.Thispreventsfloatinginputs

andeliminatestheneedforpull-up/downresistors.

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for heavy loads

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
