Présentation
Description
This IC is particularly used in applications requiring temporary data storage, data transfer, or data sequencing. Each flip-flop is equipped with a clock input that triggers on the rising edge, enabling precise timing control. The SN74HC377N also includes an enable input that controls the loading of data into the flip-flops, providing additional control for data handling tasks.
With a typical propagation delay of about 15 ns and low power consumption, the SN74HC377N is suitable for high-speed operations. Its robust design allows it to be employed in a variety of applications, including computing, industrial controls, and consumer electronics, where reliable performance and efficiency are critical.
Equivalent
1. CD74HC377 from Texas Instruments.
2. MC74HC377 from ON Semiconductor.
3. HEF377B from Nexperia.
4. TC74HC377 from Toshiba.
These alternatives provide similar functionality and are suitable for digital storage and flip-flop applications. Always check the datasheet for pin configuration and electrical characteristics before substitution.
Features
1. Octal D-Type Flip-Flop: It has eight flip-flops, each designed to capture and store data on the rising edge of the clock signal.
2. 3-State Outputs: Each flip-flop output can be set to a high-impedance state, allowing for easy interfacing with bus lines.
3. Direct Clear: Provides an asynchronous clear control, allowing the flip-flops to be reset independently of the clock signal.
4. High-Speed Operation: Utilizes advanced CMOS technology for faster data processing speeds compared to traditional logic circuits.
5. Wide Supply Voltage Range: Operates from 2V to 6V, making it versatile for different power supply configurations.
6. Low Power Consumption: Features low power dissipation due to CMOS technology, which is beneficial for battery-powered devices.
7. Input and Output Protection: Includes protection against static discharge and voltage transients.
8. Standard 20-Pin Package: Comes in a DIP-20 package suitable for through-hole mounting.
These features make the SN74HC377N a reliable choice for applications requiring data storage and management, such as memory control and microprocessor interfacing.
Pinout
1. Pin Count: 16 pins.
2. Pin Functions:
- Pins 1-8 (D0-D7): Data inputs for the 8 flip-flops.
- Pin 9 (GND): Ground.
- Pin 10 (OE, Output Enable): When low, allows data to be transferred to the outputs.
- Pins 11-18 (Q0-Q7): Outputs corresponding to each flip-flop.
- Pin 19 (CP, Clock Input): Triggers the flip-flops on the rising edge when enabled.
- Pin 20 (VCC): Supply voltage.
The SN74HC377N is used in digital circuits for temporary data storage, state retention, and data synchronization to a clock signal. The device captures and holds data present at its inputs when a clock pulse is received, provided the output enable (OE) is active.
