INDUSTRIALTEMPERATURERANGE

3.3V CMOS 18-BIT UNIVERSAL IDT74ALVCH16501

BUS TRANSCEIVER WITH

3-STATE OUTPUTS

AND BUS-HOLD

FEATURES:

DESCRIPTION:

• 0.5 MICRON CMOS Technology

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

This 18-bit universal bus transceiver is built using advanced dual metal

CMOStechnology.Dataflowineachdirectioniscontrolledbyoutput-enable

• 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 and TSSOP packages

(OEAB and OEBA), latch enable (LEAB and LEBA), and clock (CLKAB and

CLKBA)inputs. ForA-to-Bdata flow, the device operates inthe transparent

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for heavy loads

The ALVCH16501 has been designed with a ±24mA output driver. This

driveriscapableofdrivingamoderatetoheavyloadwhilemaintainingspeed

performance.

The ALVCH16501 has “bus-hold” which retains the inputs’ last state

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
