• 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

•V

CC = 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

DESCRIPTION:

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.
