Product Overview: NXP PC74HCT573T Octal D-type Transparent Latch

The NXP PC74HCT573T is a high-speed Si-gate CMOS device that is pin-compatible with low-power Schottky TTL (LSTTL). It is designed to have the same switching characteristics as the high-speed TTL family, making it ideal for interfacing with TTL logic. The device features an octal D-type transparent latch with 3-state outputs, which can be used to interface 8-bit data buses to random access memory (RAM).

Key Features:

• Logic Type: The PC74HCT573T is an octal D-type transparent latch with 3-state non-inverting outputs.
• Operating Voltage: It operates at a voltage range of 4.5V to 5.5V, which is suitable for TTL environments.
• High-Speed Performance: The device offers high-speed performance, with typical propagation delay times significantly lower than those of the LSTTL family.
• Power Consumption: It has a low power consumption, with a typical I_CC of only 4 μA in the quiescent state, making it suitable for power-sensitive applications.
• Compatibility: The latch is fully compatible with the HCT family and has the ability to drive 15 LSTTL loads.
• Package: The PC74HCT573T comes in a plastic thin shrink small outline package (TSSOP) with 20 pins, providing a compact footprint for space-constrained applications.

Applications:

The NXP PC74HCT573T is versatile and can be used in a wide range of applications. It is particularly useful in systems that require a temporary storage of data for interfacing with buses or processors. This includes:

• Computer systems
• Data communications equipment
• Control systems
• Instrumentation
