INDUSTRIAL TEMPERATURE RANGE
IDT74FCT3245/A
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
• CMOS power levels (0.4μW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Available in QSOP and TSSOP packages
DESCRIPTION:
The FCT3245/A octal transceivers are built using advanced dual metal
CMOS technology. These high-speed, low-power transceivers are ideal
for asynchronous communication between two buses (A and B). The
direction control pin (DIR) controls the direction of data flow. The output
enable pin (OE) overrides the direction control and disables both ports. All
inputs are designed with hysteresis for improved noise margin.
The FCT3245/A has series current limiting resistors. These offer low
ground bounce, minimal undershoot, and controlled output fall times-
reducing the need for external series terminating resistors.
