Enhanced-product octal D-type latches with logic-level shifter

The SN74LV8T573-EP 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.
