DESCRIPTION:
The FCT16240T/AT/CT/ET and FCT162240T/AT/CT/ET
16-bit buffer/line drivers are built using advanced dual metal
CMOS technology. These high-speed, low-power devices
offer bus/backplane interface capability with improved packing
density. The flow-through organization of signal pins simplifies
layout. The three-state controls are designed to operate these
devices in a Quad-Nibble, Dual-Byte or single 16-bit word
mode. All inputs are designed with hysteresis for improved
noise margin.
The FCT16240T/AT/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 FCT162240T/AT/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
FCT162240T/AT/CT/ET are plug-in replacements for
FCT16240T/AT/CT/ET and 54/74ABT16240 for on-board interface applications.
