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– reduc-

ing 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 in-

terface applications.
