(TOP VIEW)

The ′ABT533 are 8-bit transparent D-type latches

with 3-state outputs designed specifically for

driving highly capacitive or relatively low-

impedance loads. They are particularly suitable

for implementing buffer registers, I/O ports,

bidirectional bus drivers, and working registers.

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 inverse of the levels set up at the

D inputs. The ′ABT533 provides inverted data at

its outputs.

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 a high-impedance state. In the high-impedance state, the outputs neither load nor drive

the bus lines significantly. The high-impedance state and the 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. Previously stored data can be retained or new data

can be entered while the outputs are in the high-impedance state.

To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74ABT533 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

The SN54ABT533 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT533 is characterized for operation from –40°C to 85°C.
