|Description||Octal Transparent Latch With 3-STATE Outputs|
|Datasheet||Download 74F533SC datasheet|
The 74F533 consists of eight latches with 3-STATE outputs for bus organized system applications. The flip-flops appear transparent to the data when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW. When OE is HIGH the bus output is in the high impedance state. The 74F533 is the same as the 74F373, except that the outputs are inverted.Features

Output O0 Z The 74F533 contains eight D-type latches with 3-STATE output buffers. When the Latch Enable (LE) input is HIGH, data on the Dn inputs enters the latches. In this condition the latches are transparent, i.e., a latch output will change state each time its D input changes. When LE is LOW, the latches store the information that was present on the D inputs a setup time preceding the HIGH-to-LOW transition of LE. The 3-STATE buffers are controlled by the Output Enable (OE) input. When OE is LOW, the buffers are in the bi-state mode. When OE is HIGH the buffers are in the high impedance mode but this does not interfere with entering new data into the latches.
