3.3V CMOS OCTAL
BUFFER/LINE DRIVER
74FCT3244/A
DESCRIPTION:
FEATURES:
• 0.5 MICRON CMOS Technology
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 3.3V ±0.3V, Normal Range
• VCC = 2.7V to 3.6V, Extended Range
μW typ. static)
• CMOS power levels (0.4μ
• Rail-to-Rail output swing for increased noise margin
• Available in QSOP, SOIC, SSOP, and TSSOP packages
The FCT3244/A octal buffer/line drivers are built using advanced dual
metal CMOS technology. These high-speed, low-power buffers are
designed to be used as memory data and address drivers, clock drivers,
and bus-oriented transmitter/receivers. The three-state controls are
designed to operate these devices in a dual-nibble or single-byte mode. All
inputs are designed with hysteresis for improved noise margin.
