Product Overview: 74LVC573ABQ from NXP Semiconductors

The 74LVC573ABQ from NXP Semiconductors is a high-performance, octal D-type transparent latch with 3-state outputs. Designed for use in 1.65 V to 3.6 V V_CC operations, this device is part of the LVC family which offers low-voltage CMOS technology that is optimized for low power consumption and high-speed operation.

Key Features

• Wide Operating Voltage Range: The 74LVC573ABQ operates between 1.65 V and 3.6 V, making it suitable for interfacing with both 3.3 V and 2.5 V logic levels.
• High-Speed Performance: It offers a propagation delay of just 3.7 ns with a 5 V supply, ensuring rapid response times for critical applications.
• Low Power Consumption: The device boasts a low power consumption, with a typical I_CC of only 10 µA, even when operating at the maximum 3.6 V V_CC.
• Bus Hold Feature: Inputs are equipped with a bus hold feature, which maintains the last input state whenever the input goes to a high-impedance state, thus eliminating the need for external pull-up or pull-down resistors.
• 3-State Outputs: The octal latch includes 3-state outputs which can be placed in a high-impedance mode, allowing for bus-oriented applications.
• Latch-Up Performance: It exceeds 100 mA per JESD 78, Class II, ensuring robust performance in the field.
• ESD Protection: HBM JESD22-A114F exceeds 2000 V and MM JESD22-A115-A exceeds 200 V, providing a high level of protection against electrostatic discharge.
