DESCRIPTION:
The FCT163646/A/C 16-bit registered transceivers are
built using advanced dual metal CMOS technology. These
high-speed, low-power devices are organized as two inde-
pendant 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 FCT163646/A/C have series current limiting resistors.
This offers low ground bounce, minimal undershoot, and
controlled output fall times-reducing the need for external
series terminating resistors.

NOTES:
1. For conditions shown as Max. or Min., use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at Vcc = 3.3V, +25°C ambient.
3. Not more than one output should be tested at one time. Duration of the test should not exceed one second.
4. This parameter is guaranteed but not tested.
5. VOH = VCC –0.6V at rated current.
