DESCRIPTION
The 74LVT16652A is a high-performance BiCMOS product
designed for V
CC
operation at 3.3V. The device can be used as two
8-bit transceivers or one 16-bit transceiver.
Complimentary output-enable (OEAB and OEBA) inputs are
provided to control the transceiver functions. Select-control (SAB
and SBA) inputs are provided to select whether real-time or stored
data is transferred. A Low-input level selects real-time data, and a
High input level selects stored data. The circuitry used for select
control eliminates the typical decoding glitch that occurs in a
multiplexer during the transition between stored and real-time data.
Data on the A or B bus, or both, can be stored in the internal
flip-flops by Low-to-High transitions at the appropriate clock (CPAB
or CPBA) inputs regardless of the levels on the select-control or
output-enable inputs. When SAB and SBA are in real-time transfer
mode, it is possible to store data without using the internal D-type
flip-flops by simultaneously enabling OEAB and OEBA. In this
configuration, each output reinforces its input. Thus, when all other
data sources to the two sets of bus lines are at high impedance,
each set of bus lines remains at its last level configuration.
