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 75
n 4 kV minimum ESD immunity
