to enter data from A0–A7 or to take data from B0–B7, as indicated in the

FunctionTable. WithCEAB low, a lowsignalonthe A-to-BLatchEnable

CEBA, LEBA andOEBA inputs.

• Low input and output leakage ≤1µA (max.)

• CMOS power levels

• True TTL input and output compatibility:

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

• High Drive outputs (-15mA IOH, 64mA IOL)

• Meets or exceeds JEDEC standard 18 specifications

• Military product compliant to MIL-STD-883, Class B and DESC

listed (dual marked)

• Power off disable outputs permit "live insertion"

• Available in the following packages:

– Industrial: SOIC, SSOP, QSOP

– Military: CERDIP, LCC
