Octal Transparent D-Type Latches With 3-State OutputsThese octal transparent D-type Latches SN74HCT573 feature 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. The ?HCT573 devices 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 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 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. By Texas Instruments |
