onsemi 20-SOIC 74AC573SC

The 74AC573SC is a high-speed CMOS logic device containing eight D-type transparent latch circuits in a single 16-pin Small Outline Integrated Circuit (SOIC) package. Each latch has an individual data input (D) and three-state outputs (Q), which can be enabled or disabled by a common Output Enable (OE) pin. The latches are transparent when the Latch Enable (LE) signal is high, allowing data to pass through directly from the inputs to the outputs; when LE is low, the current data state is captured and held at the outputs until the next latch enable transition. This chip is suitable for bus-oriented applications where data needs to be stored and selectively transmitted.
