Motorola MC74ACT533DW, MC74ACT533N, MC74AC533DW, MC74AC533N Datasheet
5-1
FACT DATA
The MC74AC533/74ACT533 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
time 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 ′AC/ACT533
is the same as the ′AC/ACT373, except that the outputs are inverted. For description
and logic diagram please see the ′AC/ACT373 data sheet.
• Eight Latches in a Single Package
• 3-State Outputs for Bus Interfacing
• ′ACT533 Has TTL Compatible Inputs
• Inverted Output Version of ′ACT373
