NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Description

This 16-bit registered transceiver of the IDT74LVC16952A 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.OEAB performs 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 OEBA inputs. 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 IDT74LVC16952A has been designed with a ±24mA output driver. This driver is capable of driving a moderate to heavy load while maintaining speed performance
