BUS TRANSCEIVER/
REGISTER (3-STATE)
DESCRIPTION:
The FCT16646T 16-bit registered transceiver is built using advanced
dual metal CMOS technology. These high-speed, low-power devices are
organized as two independent 8-bit bus transceivers with 3-state D-type
registers. The control circuitry is organized for multiplexed transmission of
data between A bus and B bus either directly or from the internal storage
registers. Each 8-bit transceiver/register features direction control (xDIR),
over-riding Output Enable control (xOE) and Select lines (xSAB and xSBA)
to select either real-time data or stored data. Separate clock inputs are
provided for A and B port registers. Data on the A or B data bus, or both,
can be stored in the internal registers by the low-to-high transitions at the
appropriate clock pins. Flow-through organization of signal pins simplifies
layout. All inputs are designed with hysteresis for improved noise margin.
The FCT16646T is 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.
