description
This 16-bit registered transceiver is designed for
low-voltage (3.3-V) V
CC
operation.
The SN74LVC16543 can be used as two 8-bit
transceivers or one 16-bit transceiver. Separate
latch-enable (LEAB or LEBA) and output-enable
(OEAB or OEBA) inputs are provided for each
register to permit independent control in either
direction of data flow.
The A-to-B enable (CEAB) input must be low in
order 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 requires using the CEBA, LEBA, and OEBA inputs.
To ensure the high-impedance state during power up or power down, 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74LVC16543 is characterized for operation from –40
°
C to 85
°
C.
