DESCRIPTION:
The FCT652T 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 FCT652T
utilizes GAB and
GBA signals to control the transceiver functions.
SAB and SBA control pins are provided to select either real- time or stored
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.
