description
The ’ACT533 devices are octal transparent
D-type latches with 3-state outputs. When the
latch-enable (LE) input is high, the Q outputs
follow the complements of the data (D) inputs.
When LE is taken low, the Q
outputs are latched
at the inverted levels set up at the D inputs.
A buffered output-enable (OE
) input can be used
to place the eight outputs in either a normal logic
state (high or low logic levels) or the
high-impedance state. In the high-impedance
state, the outputs neither load nor drive the bus
lines significantly. The high-impedance state and
increased drive provide the capability to drive bus
lines without need for interface or pullup
components.
OE
does not affect the internal operations of the latches. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
The SN54ACT533 is characterized for operation over the full military temperature range of –55°C to 125°C. The
SN74ACT533 is characterized for operation from –40°C to 85°C.

‡
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51.
