description/ordering information

These octal transparent D-type latches feature 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.

While the latch-enable (LE) input is high, the Q outputs respond to the data (D) inputs. When LE is low, the

outputs are latched to retain the data that was set up.

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 interface or pullup components.

SCLS147E − DECEMBER 1982 − REVISED SEPTEMBER 2003 description/ordering information (continued) To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. OE does not affect the internal operations of the latches.
