Overview
Description
Key specifications include:
- Power Supply: Operates with a typical voltage of 5V.
- Inputs/Outputs: Consists of 8 inputs and 8 outputs, accommodating octal data storage.
- Control: Includes an active-low output enable pin (OE) which, when activated, forces the outputs into a high-impedance state.
- Package: Available in a 20-pin dual in-line package (DIP).
Applications of the SN74LS373N span from data buffering and storage to driving LEDs or other display devices in microcontrollers and microprocessor systems. Its reliable performance and ease of use make it popular in educational and industrial projects.
Equivalent
1. Fairchild's DM74LS373N
2. ON Semiconductor's MC74HC373N
3. NXP's 74HC373N
4. STMicroelectronics' M74HC373B1
5. Microchip's TC74HC373AP
These products offer similar functionality, but it's essential to verify specifications and performance characteristics to ensure compatibility for specific applications.
Features
1. High-Performance: It features Schottky-clamped TTL circuitry for high-speed operation.
2. 8-Bit Latch: Contains eight latches to provide data storage.
3. Transparent Operation: When the latch-enable (LE) input is high, the device operates in transparent mode, allowing data inputs to flow through to outputs.
4. 3-State Outputs: Outputs can be in one of three states: high, low, or high-impedance, controlled by the output-enable (OE) input.
5. Latch Enable and Output Control: The device has independent latch enable and output enable controls for flexible data handling.
6. Wide Operating Voltage: Operates typically around 5V.
7. Package Type: Available in a 20-pin Dual In-line Package (DIP).
These features make the SN74LS373N suitable for a variety of applications requiring data storage and bus interfacing.
Pinout
- Pins 1-8 (D0-D7): Data inputs for the 8-bit latch. These are the data lines that the latch will capture when enabled.
- Pin 9 (GND): Ground connection.
- Pin 11 (Q7): The output corresponding to data input D7.
- Pins 12-19 (Q6-Q0): Outputs corresponding to data inputs D6-D0 respectively.
- Pin 10 (LE): Latch Enable input. When high, the data at the inputs (D0-D7) are latched into the device.
- Pin 20 (VCC): Supply voltage.
The three-state outputs (Q0-Q7) allow for bus interfacing by enabling multiple devices to connect to the same bus line without interference, provided only one device drives the bus at a time. This is controlled by the Output Enable (OE) pin, which is typically found on pin 11 in similar devices but is not explicitly listed in the above description, possibly indicating a variation in labeling or packaging.
