SN74HC373DBR Octal Transparent D-Type Latches with 3-State Outputs
The SN74HC373DBR from Texas Instruments is a high-performance, octal transparent D-type latch with 3-state outputs designed for 2-V to 6-V VCC operation. This integrated circuit is a crucial component for systems that require the temporary storage of data. It allows for the capture and retention of the state of 8 data lines in one compact package.
Constructed with high-current outputs that can drive up to 15 LSTTL loads, the SN74HC373DBR is suitable for interfacing with a wide range of devices and is particularly well-suited for driving bus lines in a bus-organized system. Its 3-state outputs can be placed in a high-impedance state, effectively disconnecting the output from the rest of the circuit, which is useful for sharing a common bus line without risking data collision.
Key Features:
- Wide Operating Voltage Range: Designed to work with a supply voltage ranging from 2 to 6 volts, accommodating various logic level requirements.
- High-Current Outputs: Capable of driving 15 LSTTL loads, ensuring compatibility with numerous logic families.
- Octal Transparent Latches: Features 8 latches that allow for simultaneous storage and transparent transfer of data when enabled.
- 3-State Outputs: The outputs can be set to either a logical level or a high-impedance state, facilitating the connection to and disconnection from a bus line.
- Direct Clear Function: Equipped with a clear function that can reset all latches, providing a quick way to clear stored data.
- Edge-Triggered Latching: Data on the D-input is captured on the rising edge of the clock signal, ensuring reliable and timely data storage.
- Robust Packaging: The device comes in a DBR-typed package, which is a small-outline integrated circuit, providing space efficiency on PCBs.
The SN74HC373DBR is a versatile component that excels in applications where data needs to be temporarily held before being used or transferred elsewhere. Its ability to interface with multiple logic levels and its robust output drive make it a reliable choice for system designers. Whether you're building complex computing systems or simple logic controllers, the SN74HC373DBR is engineered to meet the demands of a wide array of data storage and transfer applications.
