DESCRIPTION:
The FCT646T/FCT2646T/FCT648T/FCT652T/2652T con-
sist 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 regis-
ters.
The FCT652T/FCT2652T utilize GAB and
GBA
signals to
control the transceiver functions. The FCT646T/FCT2646T/
FCT648T utilize the enable control (
G
) and direction (DIR)
pins 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 appro-
priate clock pins (CPAB or CPBA), regardless of the select or
enable control pins.
The FCT26xxT have balanced drive outputs with current
limiting resistors. This offers low ground bounce, minimal
undershoot and controlled output fall times-reducing the need
for external series terminating resistors. FCT2xxxT parts are
plug-in replacements for FCTxxxT parts.
