Enhanced Versions

The IDT54/74FCT646/A/C 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 IDT54/74FCT646/A/C utilizes 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

appropriate clock pins (CPAB or CPBA) regardless of the

select or enable control pins.

• Military product compliant to MIL-STD-883, Class B
