The PI74FCT16240T, PI74FCT162240T, and PI74FCT162H240T are inverting 16-bit buffer/line drivers designed for applications driving high capacitance loads and low impedance backplanes. These high-speed, low power devices offer bus/backplane interface capability and a flow-through organization for ease of board layout. These devices are designed with three-state controls to operate in a Quad-Nibble, Dual-Byte, or a single 16-bit word mode. The PI74FCT16240T output buffers are designed with a Power- Off disable allowing “live insertion” of boards when used as backplane drivers. The PI74FCT162240T has ±24 mA balanced output drivers. It is designed with current limiting resistors at its outputs to control the output edge rate resulting in lower ground bounce and undershoot. This eliminates the need for external terminating resistors for most interface applications. The PI74FCT162H240T has “Bus Hold” which retains the input's last state whenever the input goes to high-impedance preventing “floating” inputs and eliminating the need for pull-up/down resistors. 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 1234567890123456789012345678901212345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901 2123456789012 Logic Block Diagram Product Features: Common Features:
