SN54HC573A

具有三态输出的八路 D 类透明锁存器; • 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.
