Visão Geral
Description
The device also includes a 3-state output control, allowing for easy connection to shared buses. When the output-enable (OE) input is high, the outputs are in the high-impedance state, effectively disconnecting them from the bus, and when OE is low, the outputs reflect the latch's state.
The SN74HCT373N is designed to be pin-compatible with the older 74HC series, making it a versatile choice for upgrades in existing systems. It is commonly used in digital systems where data storage and retrieval with controlled output is necessary.
Equivalent
1. 74HC373
2. CD74HCT373
3. MC74HCT373A
4. TC74HCT373
5. HEF473
These components generally share similar functionality, pin configuration, and electrical characteristics, making them suitable substitutes in various applications. Always verify specific requirements and datasheet specifications for compatibility.
Features
1. Logic Family: It belongs to the HCT (High-speed CMOS with TTL-compatible inputs) logic family, allowing compatibility with TTL logic levels.
2. Voltage Range: Operates over a wide supply voltage range from 4.5V to 5.5V, making it suitable for standard 5V applications.
3. High-Speed Operation: Delivers fast operation with propagation delays typically around 15ns.
4. 3-State Outputs: The outputs can be configured for high, low, or high-impedance states, enabling bus-oriented applications.
5. Latch Enable: Features a latch enable input that controls the latching of data, providing control over data flow and storage.
6. Outputs: Offers eight latches in a single package allowing multiple bits of data to be stored simultaneously.
7. Pin Configuration: Housed in a 20-pin DIP (Dual In-line Package) for easy integration into circuits.
8. Temperature Range: Designed for operation over a temperature range from -40°C to 85°C, suitable for various environmental conditions.
These features make the SN74HCT373N ideal for applications requiring storage of multiple bits of data, interfacing with microprocessors, and controlling data flow in digital systems.
Pinout
1. Pin 1 (OE̅): Output Enable, active low. When low, the outputs are enabled; when high, the outputs are in a high-impedance state.
2. Pin 2-9 (Q0-Q7): These are the data output pins. They output the stored data when the latch is enabled.
3. Pin 10 (GND): Ground connection.
4. Pin 11-18 (D0-D7): Data inputs. These accept the input data that will be latched.
5. Pin 19 (LE): Latch Enable. When high, the latch is transparent and allows data to flow from input to output; when low, the data is latched.
6. Pin 20 (VCC): Supply voltage.
The device is used in applications where data needs to be stored temporarily and transferred between registers, commonly in microprocessor and computer systems.
