SN74HC573A

具有三態(tài)輸出的八路透明 D 型鎖存器; ? Wide Operating Voltage Range from 2 V to 6 V\n? High-Current 3-State Outputs Drive Bus Lines Directly up to 15 LSTTL Loads\n? Low Power Consumption: 80-μA Maximum ICC\n? Typical tpd = 21 ns\n? ±6-mA Output Drive at 5 V\n? Low Input Current: 1 μA (Maximum)\n? Bus-Structured Pinout;

The SNx4HC573A devices are octal transparent D-type latches that 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.

汽車類具有三態(tài)輸出的八路透明 D 類鎖存器; ? Qualified for Automotive Applications\n? Wide Operating Voltage Range of 2 V to 6 V\n? High-Current 3-State Outputs Drive Bus Lines Directly or up to 15 LSTTL Loads\n?

This octal transparent D-type latch features 3-state outputs designed specifically for driving highly capacitive or relatively low-impedance loads. It is 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. 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. Old data can be retained or new data can be entered while the outputs are in the high-impedance state.
