CD74AC573M Description

The CD74AC573M from Texas Instruments is a high-performance 8-bit transparent D-type latch designed for surface-mount applications. Part of the 74AC series, it operates across a wide voltage range (1.5V to 5.5V), making it versatile for mixed-voltage systems. This RoHS3-compliant IC features 3ns propagation delay and symmetrical 24mA output drive (high and low), ensuring robust signal integrity in high-speed digital circuits. Packaged in a 20-pin SOIC tube, it is ideal for space-constrained designs. With REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity, it suits long-term storage and harsh environments.

CD74AC573M Features

• High-Speed Operation: 3ns propagation delay enables efficient data transfer in time-critical applications.
• Wide Voltage Range (1.5V–5.5V): Compatible with TTL and CMOS logic levels, reducing need for level shifters.
• Balanced Output Drive: 24mA sink/source current ensures strong signal integrity even under heavy loads.
• Transparent Latching: Real-time data transfer when enabled, with hold capability when disabled.
• Robust Packaging: 20-pin SOIC offers durability and ease of assembly in automated PCB production.
• Low Power Consumption: Optimized for energy-efficient designs without sacrificing performance.

CD74AC573M Applications

• Data Buffering: Ideal for microprocessor/microcontroller interfaces to stabilize data buses.
