IDT74LVCR16952A
DESCRIPTION:
This 16-bit registered transceiver is built using advanced dual metal
CMOS technology. This high-speed, low power device is organized as two
independent 8-bit D-type registered transceivers with separate input and
output control for independent control of data flow in either direction. For
example, the A-to-B Enable (CEAB) must be LOW to enter data from the A
port.CLKABcontrolstheclockingfunction. WhenCLKABtogglesfromLOW-
to-HIGH, the data present on the A port will be clocked into the register.
OEAB performs the output enable function on the B port. Data flow from the
BporttoAportissimilarbutrequiresusingCEBA,CLKBA,andOEBAinputs.
Full 16-bit operation is achieved by tying the control pins of the independent
transceivers together.
All pins can be driven from either 3.3V or 5V devices. This feature allows
the use of this device as a translator in a mixed 3.3V/5V supply system.
The LVCR162952A has series resistors in the device output structure
which will significantly reduce line noise when used with light loads.This
driver has been developed to drive ±12mA at the designated threshold
levels.
