APPLICATIONS:
•
3.3V High Speed Systems
•
3.3V and lower voltage computing systems
This 16-bit registered transceiver is built using advanced dual metal
CMOS technology. The ALVCHR16543 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 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 CEBA, LEBA,
and OEBA.
The ALVCHR16543 has series resistors in the device output struc-
ture which will significantly reduce line noise when used with light loads.
This driver has been designed to drive ±12mA at the designated
threshold levels.
The ALVCHR16543 has “bus-hold” which retains the inputs’ last state
whenever the input bus goes to a high impedance. This prevents
floating inputs and eliminates the need for pull-up/down resistors.
