DESCRIPTION:
The FCT162240T 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 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 is a plug-in replacement for FCT16240T and 74ABT16240 for on-board interface applications.
