The

CC
operation, but with the capability to provide a TTL
interface to a 5-V system environment. These
devices can be used as two 8-bit transceivers or
one 16-bit transceiver. Separate latch-enable
(LEAB or LEBA), output-enable (OEAB or OEBA),
and chip-enable (CEAB or CEBA) inputs are
provided for each register to permit independent
control in either direction of data flow.
’ALVTH16543
are
16-bit
registered
The A-to-B enable (CEAB) input must be low to enter data from A or to output data from B. If CEAB is low and
LEAB is low, the A-to-B latches are transparent; a subsequent low-to-high transition of LEAB puts the A latches
in the storage mode. With CEAB and OEAB both low, the 3-state B outputs are active and reflect the data present
at the output of the A latches. Data flow from B to A is similar but uses the CEBA, LEBA, and OEBA inputs.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
When V
CC
is between 0 and 1.2 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 1.2 V, OE should be tied to V
CC
through a pullup resistor;
the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ALVTH16543 is available in TI’s thin very small-outline package (DGV), which provides the same I/O
pin count and functionality of standard Widebus packages in less than half the printed circuit board area.
The SN54ALVTH16543 is characterized for operation over the full military temperature range of –55
°
C to
125
°
C. The SN74ALVTH16543 is characterized for operation from –40
°
C to 85
°
C.
