74LVQ244
Low Voltage Octal Buffer/Line Driver with 3-STATE
Outputs
General Description
The LVQ244 is an octal buffer and line driver designed to be
employed as a memory address driver, clock driver and bus
oriented transmitter or receiver which provides improved PC
board density.
Features
n Ideal for low power/low noise 3.3V applications
n Implements patented EMI reduction circuitry
n Available in SOIC JEDEC, SOIC EIAJ and QSOP
packages
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Improved latch-up immunity
n Guaranteed incident wave switching into 75Ω
n 4 kV minimum ESD immunity

Note 9: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The speci-
fication applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH). Parameter guaranteed by design.
