FEATURES:
DESCRIPTION:
• 0.5 MICRON CMOS Technology
• High-speed, low-power CMOS replacement for ABT functions
• Typical tSK(o) (Output Skew) < 250ps
• Low input and output leakage ≤1µA (max.)
• ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
• VCC = 5V ±10%
The FCT162652T16-bitregisteredtransceivers are builtusingadvanced
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit bus transceivers with 3-state D-type
registers.Forexample,thexOEABandxOEBAsignalscontrolthetransceiver
functions.
The xSAB and xSBA control pins are provided to select either real time or

• Balanced Output Drivers:
– ±24mA(industrial)
– ±16mA(military)
• Reduced system switching noise
• Typical VOLP (Output Ground Bounce) < 0.6V at VCC = 5V,
TA = 25°C
• Available in the following packages:
– Industrial: SSOP, TSSOP
