DESCRIPTION:
The IDT54/74FCT163652/A/C 16-bit registered transceiv-
ers are built using advanced dual metal CMOS technology.
These high-speed, low-power devices are organized as two
independent 8-bit bus transceivers with 3-state D-type regis-
ters. For example, the xOEAB and x
OEBA
signals control the
transceiver functions.
The xSAB and xSBA 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 level 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 (xCLKAB or xCLKBA), regardless of the
select or enable control pins. Flow-through organization of
signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
The IDT54/74FCT163652/A/C have series current limiting
resistors. This offers low ground bounce, minimal under-
shoot, and controlled output fall times鈥搑educing the need for
external series terminating resistors.
