74ALVC373 Octal D-type transparent latch 3-state Rev. 02 18 October 2007 Product data sheet 1. General description The 74ALVC373 is an octal D-type transparent latch featuring separate D-type inputs for each latch and 3-state true outputs for bus-oriented applications. A latch enable (LE) input and an outputs enable (OE) input are common to all latches. When pin LE is HIGH, data at the D-inputs (pins D0 to D7) enters the latches. In this condition, the latches are transparent, that is, a latch output will change each time its corresponding D-input changes. When pin LE is LOW, the latches store the information that was present at the D-inputs one set-up time preceding the HIGH-to-LOW transition of pin LE. When pin OE is LOW, the contents of the eight latches are available at the Q-outputs (pins Q0 to Q7). When pin OE is HIGH, the outputs go to the high-impedance OFF-state. Operation of input pin OE does not affect the state of the latches. The 74ALVC373 is functionally identical to the 74ALVC573, but has a different pin arrangement. 2.
