FEATURES:
DESCRIPTION:
• Common features:
– 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)
– Packages include 25 mil pitch SSOP, 19.6 mil pitch
TSSOP, 15.7 mil pitch TVSOP and 25 mil pitch Cerpack
– Extended commercial range of -40°C to +85°C
– VCC = 5V ±10%
• Features for FCT16823AT/BT/CT/ET:
– High drive outputs (-32mA IOH, 64mA IOL)
– Power off disable outputs permit “live insertion”
– Typical VOLP (Output Ground Bounce) < 1.0V at
VCC = 5V, TA = 25°C
• Features for FCT162823AT/BT/CT/ET:
– Balanced Output Drivers: ±24mA (commercial),
±16mA (military)
– Reduced system switching noise
– Typical VOLP (Output Ground Bounce) < 0.6V at
VCC = 5V,TA = 25°C
The FCT16823AT/BT/CT/ET and FCT162823AT/BT/CT/
ET 18-bit bus interface registers are 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.
The FCT16823AT/BT/CT/ET are ideally suited for driving
high-capacitance loads and low-impedance backplanes. The
output buffers are designed with power off disable capability
to allow "live insertion" of boards when used as backplane
drivers.
The FCT162823AT/BT/CT/ET have 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
FCT162823AT/BT/CT/ET are plug-in replacements for the
FCT16823AT/BT/CT/ET and ABT16823 for on-board interface applications.
