TRANSCEIVER/
REGISTER (3-STATE)
DESCRIPTION:
The FCT646T consists of a bus transceiver with 3-state D-type flip-flops
and control circuitry arranged for multiplexed transmission of data directly
from the data bus or from the internal storage registers. The FCT646T
utilizes the enable control (G) and direction (DIR) pins to control the
transceiver functions.
SABandSBAcontrolpinsareprovidedtoselecteitherreal-timeorstored
data transfer. The circuitry used for select control will eliminate the typical
decoding glitch that occurs in a multiplexer during the transition between
stored and real-time data. A low input level selects real-time data and a high
selects stored data.
Data on the A or B data bus, or both, can be stored in the internal D flip-
flops by low-to-high transitions at the appropriate clock pins (CPAB or
CPBA), regardless of the select or enable control pins.
