74LVC573A

The 74LVC573A from N-A is an octal transparent D-type latch designed for general-purpose logic applications. It features eight transparent D-type latches where the Q outputs follow the D inputs while the latch-enable (LE) is high. When LE is low, the Q outputs are latched.

This device operates with a supply voltage range of 1.65V to 3.6V and offers inputs tolerant to 5.5V, enabling mixed-voltage applications. The outputs can sink or source 24mA at 3V. It includes a buffered output-enable (OE) input to place outputs in a normal logic state or a high-impedance state, which is beneficial for bus driving without significant loading.

The 74LVC573A is available in a TSSOP-20 package suitable for surface mounting. It supports partial power-down applications with I OFF circuitry and features Schmitt trigger action at all inputs. ESD protection is tested per JESD 22, exceeding 2000V for the Human Body Model.

Key features include low power consumption, I OFF support for partial power-down, and the ability to retain data while outputs are in a high-impedance state. The device is designed for applications such as PCs, notebooks, networking equipment, and consumer electronics like TVs and DVD players.
