Description
Pericom Semiconductor’s PI74FCT16244T and PI74FCT162244T
are non-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 PI74FCT16244T output buffers are designed with a Power-
Off disable allowing “live insertion” of boards when used as
backplane drivers.
The PI74FCT162244T has ±24mA 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.
