Note:
Stresses greater than those listed under 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.

Pericom Semiconductor's PI74LPT series of logic circuits are produced in the Company's advanced 0.6 micron CMOS technology, achieving industry leading speed grades.

The PI74LPT16952 is a 16-bit registered transceivers organized with two sets of eight D-type latches with separate input and output controls for each set. For data flow from A to B, for example, the Ato- B Enable (xCEAB) input must be LOW to enter data from xAx.

The data of PI74LPT16952 present on the A port will be clocked on the B register when xCLKAB toggles from LOW-to-HIGH. The xOEAB control performs the output enable function on the B port. Control of data from B to A is similar, but uses the xCEAB, xCLKAB, and xOEAB inputs. By connecting the control pins of the two independent transceivers together, a full 16-bit operation can be achieved. The output buffers of PI74LPT16952 are designed with a Power-Off disable allowing "live insertion" of boards when used as backplane drivers.

The PI74LPT16952 can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3/5.0V system.
