Description
When the latch enable (LE) is activated, the outputs follow the inputs, allowing data to pass through. When LE is deactivated, the last input values are stored, and the outputs maintain those values until LE is activated again. This feature is useful for temporary data storage during data processing.
The device is designed for a wide range of applications, including data buffering, temporary storage, and signal processing in digital circuits. It operates with a supply voltage of 4.75V to 5.25V and boasts fast switching times, making it suitable for high-speed applications. Its 20-pin DIP package allows for easy integration into various electronic designs.
Equivalent
1. SN74ALS373
2. SN74F373
3. SN74HC373
4. SN74HCT373
These alternatives may vary in technology (LS, ALS, F, HC, HCT) but function similarly. Always check specific datasheets for compatibility in your application.
Features
1. Data Latching: It can hold eight bits of data when the latch enable (LE) signal is high, making it ideal for temporary data storage.
2. Transparent Mode: When LE is high, data is passed to the outputs; when LE is low, the data is latched, allowing for stable output.
3. Compatibility: It is part of the Low Power Schottky TTL family, providing faster switching times and reduced power consumption.
4. Active-Low Enable: The output enable (OE) is active low, allowing for controlled output activation.
5. High-Speed Operation: Typical propagation delay is around 10 ns, suitable for high-speed digital applications.
6. Tri-State Outputs: Outputs can be placed in a high-impedance state, enabling multiple devices to connect to the same bus.
7. Pin Configuration: Comes in a 20-pin Dual In-Line Package (DIP) for easy integration.
8. Temperature Range: Rated for operation from 0°C to 70°C.
These features make the SN74LS373DWR suitable for a variety of digital circuit applications.
Pinout
- Pin Count: 20 pins
- Functionality: It consists of eight D-type latches that are transparent when the enable (E) pin is high. When E goes low, the latches hold the last state of the inputs.
- Input Pins: There are 8 data input pins (D0 to D7).
- Output Pins: There are 8 output pins (Q0 to Q7).
- Control Pins: It includes an Enable pin (E) for latch control and an active low output enable pin (OE) that allows for tri-state output.
This device is commonly used in applications requiring temporary data storage and manipulation, such as in data bus management and temporary data holding for processing.
