74LVT573

3.3 V octal D-type transparent latch; 3-state

The 74LVT573 is an 8-bit D-type transparent latch with 3-state outputs. The device features latch enable (LE) and output enable (OE) inputs. When LE is HIGH, data at the inputs enter the latches. In this condition the latches are transparent, a latch output will change each time its corresponding D-input changes. When LE is LOW the latches store the information that was present at the inputs a set-up time preceding the HIGH-to-LOW transition of LE. A HIGH on OE causes the outputs to assume a high-impedance OFF-state. Operation of the OE input does not affect the state of the latches. Bus hold data inputs eliminate the need for external pull-up resistors to define unused inputs

Features and benefits

  • Wide supply voltage range from 2.7 to 3.6 V
