FAST CMOS 16-BIT
BUFFER/LINE DRIVER
DESCRIPTION:
The FCT162240T/AT/CT/ET 16-bit buffer/line driver is 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 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 appli-
cations.
