The 74ALS373 is a high-performance integrated circuit designed and manufactured by NXP Semiconductors. This device belongs to the Advanced Low-Power Schottky (ALS) logic family, which is renowned for its excellent speed-power combination compared to traditional TTL logic families. The 74ALS373 is an octal transparent D-type latch with 3-state outputs.
Key Features
- Octal D-Type Latch: The device contains eight latches with D-type inputs and outputs, allowing for the simultaneous storage of eight bits of data.
- Transparent Latch: When the enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is taken low, the data that meets the setup time is latched at the Q outputs.
- 3-State Outputs: This feature allows the outputs to assume a high impedance state in addition to the active high and low logic levels, facilitating the connection of multiple outputs to a common bus without interference.
- Low Power Consumption: The ALS technology ensures that the device operates with lower power consumption without sacrificing speed, making it ideal for power-sensitive applications.
- Wide Operating Voltage Range: The 74ALS373 can operate over a wide voltage range, typically from 4.5V to 5.5V, providing flexibility in various system designs.
- Fast Propagation Delay: The device offers fast propagation delays, ensuring quick response times for high-speed operations.
Applications
The 74ALS373 is suitable for a wide range of applications, including:
- Buffering and storage of data in computer systems
- Interface between different logic levels or signal domains
- Temporary data storage for digital signal processing
- Control systems where data needs to be held temporarily
