IDT74ALVCHR162245

DESCRIPTION:

FEATURES:

This 16-bit bus transceiver is built using advanced dual metal CMOS

technology. The ALVCHR162245 device is designed for asynchronous

communicationbetweendatabuses. Thecontrol-functionimplementation

minimizesexternaltimingrequirements.

• 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)

• VCC = 3.3V ± 0.3V, Normal Range

• VCC = 2.7V to 3.6V, Extended Range

• VCC = 2.5V ± 0.2V

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

transceiver. 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.Theoutput-enable(OE)inputcanbeusedtodisablethedevice

so that the buses are effectively isolated.

The ALVCHR162245 has series resistors in the device output structure

which will significantly reduce line noise when used with light loads. This

driverhasbeendesignedtodrive±12mAatthedesignatedthresholdlevels.

The ALVCHR162245 has “bus-hold” which retains the inputs’ last state

whenever the input bus goes to a high impedance. This prevents floating

inputs and eliminates the need for pull-up/down resistors.

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

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

• Available in TSSOP package

DRIVE FEATURES:

• Balanced Output Drivers: ±12mA

• Low Switching Noise

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
