74FCT162646T/AT/CT/ET 16-bit registered transceivers are
built using advanced dual metal CMOS technology. These
high-speed, low-power devices are organized as two inde-
pendent 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 fea-
tures direction control (xDIR), over-riding Output Enable con-
trol (x
OE
) 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 IDT54/74FCT16646T/AT/CT/ET are 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.
The IDT54/74FCT162646T/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 IDT54/74FCT162646T/AT/CT/ET are plug-in
replacements for the IDT54/74FCT16646T/AT/CT/ET and
54/74ABT16646 for on-board bus interface applications.
