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
s Ideal for low power/low noise 3.3V applications
s Implements patented EMI reduction circuitry
s Available in SOIC JEDEC, SOIC EIAJ and QSOP pack-
ages
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Improved latch-up immunity
s Guaranteed incident wave switching into 75
s 4 kV minimum ESD immunity
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
