概述

Description

The SN74LVC373APWR is an octal transparent latch designed for high-speed data transfer. It features eight D-type latches with a common enable input, allowing for the storage of data on the high-to-low transition of the enable signal. This device operates with a supply voltage range of 2.3V to 3.6V, making it suitable for low-power applications.
Key features include:
- High-speed operation with fast propagation delays.
- Low power consumption, ideal for battery-operated devices.
- Wide input voltage levels compatible with various logic families.
- Outputs are 3-state, reducing contention in bus systems.
Applications include data buffering, temporary data storage, and interfacing between different logic levels in digital circuits. The SN74LVC373APWR is commonly used in consumer electronics, automotive systems, and industrial automation due to its reliability and efficiency. It is available in a TSSOP-20 package, which is compact and suitable for space-constrained designs.

Features

The SN74LVC373APWR is an octal transparent latch designed for high-speed applications. Key features include:
1. Octal Latch: It includes eight latches that allow data to be stored and output simultaneously.
2. Low Voltage Operation: Supports a wide range of supply voltages from 1.65V to 3.6V, making it suitable for low-power applications.
3. High-Speed Performance: Offers rapid data transfer with propagation delays as low as 3.5 ns at 3.3V.
4. 3-State Outputs: Outputs can be placed in a high-impedance state, allowing for multiple devices to share the same bus.
5. Transparent Mode: In this mode, the output follows the input data as long as the latch enable (LE) signal is active.
6. TTL Compatibility: Compatible with TTL logic levels, enhancing versatility in mixed-signal environments.
7. Pin Configuration: Available in a compact TSSOP package, suitable for space-constrained designs.
This device is ideal for applications requiring data storage while maintaining high-speed performance.

Package

The SN74LVC373APWR is packaged in a TSSOP (Thin Shrink Small Outline Package) with 20 pins. The "PWR" designation indicates a lead-free, green package suitable for surface mounting.

Pinout

The SN74LVC373APWR is a 20-pin integrated circuit. It functions as an octal transparent latch with 3-state outputs, designed for use in low-voltage applications. The device features an 8-bit data input (D0-D7), an active-high latch enable (LE), an active-high output enable (OE), and 8-bit data output (Q0-Q7).
The pin configuration includes:
- Pins 1-8: Data inputs (D0-D7)
- Pin 9: Latch Enable (LE)
- Pin 10: Output Enable (OE)
