DESCRIPTION:
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) con-
trols 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 mar-
gin.
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 – reduc-
ing 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 inter-
face applications.
