DESCRIPTION

· The 74LVC573A is an octal transparent D-type latch with 3-state outputs. It features eight transparent D-type latches where the Q outputs follow the D inputs when the latch-enable (LE) is high. When LE is low, the Q outputs are latched at the logic levels of the D inputs. The output-enable (OE) input controls the state of the outputs, allowing them to be in a normal logic state or a high-impedance state, which is useful for driving bus lines without additional components. The device operates within a power supply range of 1.65V to 3.6V and is tolerant to 5.5V inputs, making it suitable for mixed voltage environments. It also supports partial power-down applications with its I_OFF feature, which prevents damaging current backflow when the device is powered down.

FEATURES
