Product Description

Pericom Semiconductor’s PI74LCX series of logic circuits are produced in the Company’s advanced 0.6 micron CMOS technology, achieving industry leading speed grades.

The PI74LCX573 is an 8-bit transparent latch designed with 3-state outputs and is intended for bus oriented applications. When Latch Enable (LE) is HIGH, the flip-flops appear transparent to the data. The data that meets the set-up time when LE is LOW is latched. When OE is HIGH, the bus output is in the high impedance state.

The PI74LCX573 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.

Maximum Ratings

(Above which the useful life may be impaired. For user guidelines, not tested.)

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.

3.3V 8-BIT TRANSPARENT LATCH

Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.

2. Typical values are at VCC = 3.3V, +25°C ambient.

3. Per TTL driven input; all other inputs at VCC or GND.
