Description
Equivalent
1. 74HC273 series from Nexperia or ON Semiconductor
2. CD74HCT273 from Texas Instruments
3. HEF40273B from NXP
4. MC74HC273A from ON Semiconductor
These alternatives are generally pin-compatible and have similar electrical characteristics, but always check the datasheet for specific details and compatibility with your application.
Features
1. Octal Data Storage: It features eight edge-triggered D-type flip-flops with a common clock input, allowing simultaneous data storage of eight bits.
2. Positive-Edge Triggered: Data is loaded on the rising edge of the clock input.
3. Clear Function: It includes an asynchronous clear input that can reset all outputs to a low state, regardless of the clock.
4. TTL-Compatible: Designed for compatibility with TTL logic levels, making it suitable for interfacing with various digital systems.
5. Output Drive: The device provides totem-pole outputs capable of driving 10 standard TTL loads.
6. High-Speed Operation: Operates at high speeds suitable for typical digital logic applications.
7. Wide Operating Temperature Range: Reliable operation over a range of industrial temperatures.
8. Package Options: Available in various package types, including a 20-pin SOIC (DWR) surface-mount package.
These features make it suitable for applications requiring temporary data storage and synchronization in digital systems.
Pinout
Key features include:
- 8-bit storage capacity.
- Positive edge-triggered operation.
- Direct clear capability to reset all outputs simultaneously.
- Standard TTL compatibility for easy integration with other TTL components.
The pin configuration typically includes pins for the clock input, clear input, data inputs (D0 to D7), and outputs (Q0 to Q7), along with power supply (Vcc) and ground (GND) pins. This configuration allows the SN74LS273DWR to be used in synchronous data storage and transfer applications.
