IDT74LVCR16952A

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. CLKAB controls the clocking function. When CLKAB toggles from LOWto- HIGH, the data present on the A port will be clocked into the register. OEABperforms the output enable function on the B port. Data flow from the B port to A port is similar but requires using CEBA, CLKBA, and OEBAinputs. 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.
