DESCRIPTION
dual metal CMOS technology. The LVCH16543A 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 the A
port or to output data from the B port. LEAB controls the latch function. When
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. OEAB performs
output enable function on the B port. Data flow from the B port to the A port
is similar but requires using CEBA, LEBA, and OEBA inputs. Flow-through
organization of signal pins simplifies layout. All inputs are designed with
hysteresis for improved noise margin.
or 5V devices. This feature allows the use of this device as a translator in
a mixed 3.3V/5V supply system.
driver is capable of driving a moderate to heavy load while maintaining
speed performance.
whenever the input goes to a high impedance. This prevents floating inputs
and eliminates the need for pull-up/down resistors.
