Latches

SN74AC373N Description

The SN74AC373N from Texas Instruments is a high-performance 8-bit transparent D-type latch with 3-state outputs, designed for 2V to 6V operation. Housed in a 20-pin DIP (Dual In-line Package), this latch is part of the 74AC series, known for its low power consumption and high-speed operation with a propagation delay of just 7.5ns. It features independent circuits with 8:8 parallel input/output capability, making it ideal for data buffering and temporary storage in digital systems. The device is RoHS3 compliant and REACH unaffected, ensuring environmental and regulatory compliance.

SN74AC373N Features

• Wide Voltage Range (2V–6V): Supports flexible power supply configurations.
• High Drive Strength: 24mA output current (both high and low) for robust signal integrity.
• 3-State Outputs: Allows bus-oriented applications with output disable functionality.
• Low Propagation Delay (7.5ns): Ensures high-speed data transfer.
• Through-Hole Mounting (DIP): Simplifies prototyping and breadboarding.
• Industrial-Grade Reliability: Moisture Sensitivity Level (MSL) Not Applicable, suitable for harsh environments.
• Transparent Latching: Data passes through when the latch enable (LE) is high, simplifying timing control.

SN74AC373N Applications

The SN74AC373N excels in applications requiring temporary data storage or bus interfacing, including:

• Microprocessor/Microcontroller Systems: Acts as an address/data buffer in bus architectures.
• Memory Interfacing: Used in RAM/ROM address latching for stable data retention.
• Industrial Control Systems: Provides noise immunity and high drive capability for PLCs and motor controllers.
• Communication Equipment: Facilitates signal gating in routers and switches.
• Automotive Electronics: Suitable for low-voltage, high-speed control logic in infotainment and ADAS.

Conclusion of SN74AC373N

The SN74AC373N stands out for its high-speed performance, robust output drive, and versatile voltage range, making it a reliable choice for digital logic applications. Its 3-state outputs and transparent latching simplify system design, while its through-hole package ensures ease of integration in prototyping. Whether used in embedded systems, industrial automation, or communication hardware, this latch delivers efficiency and reliability, backed by Texas Instruments' quality assurance.
