Integrated Device Technology, Inc.
FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
• ESD > 2000V per MIL-STD-883, Method 3015;
> 200V using machine model (C = 200pF, R = 0)
• 25 mil Center SSOP Packages
• Extended commercial range of -40°C to +85°C
• VCC = 3.3V ±0.3V, Normal Range or
VCC = 2.7V to 3.6V, Extended Range
• CMOS power levels (0.4µW typ. static)
• Rail-to-Rail output swing for increased noise margin
• Military product compliant to MIL-STD-883, Class B
The FCT3827A/B 10-bit bus drivers are built using an
advanced dual metal CMOS technology. These high speed,
low power buffers are ideal for high-performance bus interface
buffering for wide data/address paths or buses carrying parity.
The 10-bit buffers have NAND-ed output enables for maximum control flexibility.
All of the FCT3827 high performance interface components are designed for high-capacitance load drive capability,
while providing low-capacitance bus loading at both inputs
and outputs.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, +25°C ambient.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. This parameter is guaranteed but not tested.
5. VOH = VCC –0.6V at rated current.

2. Minimum limits are guaranteed but not tested on Propagation Delays.
3. Propagation Delays and Enable/Disable times are with VCC = 3.3V ±0.3V, Normal Range. For VCC = 2.7V to 3.6V, Extended Range, all Propagation Delays
and Enable/Disable times should be degraded by 20%.
