The FCT162823T 18-bit bus interface register is built using advanced,
dual metal CMOS technology. These high-speed, low-power registers with
clock enable (xCLKEN) and clear (xCLR) controls are ideal for parity bus
interfacing in high-performance synchronous systems. The control inputs
are organized to operate the device as two 9-bit registers or one 18-bit
register. Flow-through organization of signal pins simplifies layout. All inputs
are designed with hysteresis for improved noise margin.

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 ≤1µ A (max.)
ESD > 2000V per MIL-STD-883, Method 3015; > 200V using
machine model (C = 200pF, R = 0)
VCC = 5V ±10%
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, TVSOP
• Military: CERPACK
The FCT162823T has balanced output drive with current limiting
resistors. This offers low ground bounce, minimal undershoot, and controlled output fall times – reducing the need for external series terminating
resistors. The FCT162823T is a plug-in replacement for the FCT16823T
and ABT16823 for on-board interface applications.
