IC 74HC SN74HC573AN (hàng xịn TI)

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.
