3.3V CMOS

IDT74ALVCH245

OCTAL BUS TRANSCEIVER

WITH 3-STATE OUTPUTS

AND BUS-HOLD

DESCRIPTION:

FEATURES:

–

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

This octal bus transceiver is built using advanced dual metal CMOS

technology.The three-state controls are designedtooperate this device

inasingle-bytemode.Allinputs aredesignedwithhysteresis forimproved

noisemargin.

–

TheALVCH245is designedforasynchronous communicationbetween

data buses.The device transmits data fromthe Abus tothe Bbus orfrom

the Bbus tothe Abus,dependingonthe logiclevelatthe direction-control

(DIR) input.

= 2.7V to 3.6V, Extended Range

VCC = 2.5V ±0.2V

CMOS power levels (0.4µW typ. static)

Rail-to-Rail output swing for increased noise margin

Available in SOIC, SSOP, QSOP, and TSSOP packages

The ALVCH245 has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speedperformance.

Drive Features for ALVCH245:

–

High Output Drivers: ±24mA

Suitable for heavy loads

The ALVCH245 has “bus-hold” which retains the inputs’ last state

wheneverthe inputbus goes toa highimpedance.This prevents floating

inputs andeliminates the needforpull-up/downresistors.

APPLICATIONS:

• 3.3V High Speed Systems

• 3.3Vandlowervoltagecomputingsystems
