SN74LVC828ADBRE4 - Texas Instruments

The SN74LVC828ADBRE4 is a high-performance, 10-bit bus interface register from Texas Instruments designed to operate on very low power. This integrated circuit is part of Texas Instruments' SN74LVC family, which is known for its devices that combine low-voltage operation with robust performance characteristics.

Fabricated with an advanced BiCMOS technology, the SN74LVC828ADBRE4 is optimized for 2.7 V to 3.6 V V_CC operation, making it particularly suitable for interfacing with 3.3 V systems. Its low-voltage operation does not compromise speed, as this device is capable of supporting data rates that accommodate modern high-speed signal processing requirements.

The SN74LVC828ADBRE4 features a 10-bit wide universal bus interface with 3-state outputs. The 3-state outputs allow for direct connection to a bus-structured system, providing high-impedance states when needed. This facilitates bus arbitration and sharing, which is critical in multi-master systems. The device has two output-enable (OE) inputs that control the transceiver function. When OE is low, the device passes data from the A inputs to the B outputs, and when OE is high, the B outputs are in the high-impedance state.

The register is edge-triggered, capturing data on the rising edge of the clock (CLK) input, which ensures synchronized data transfer within the system. Additionally, the SN74LVC828ADBRE4 supports live insertion and withdrawal (hot plugging), which is essential for high-availability systems that require maintenance or upgrades without power-down.

This device comes in a DB (SSOP – Shrink Small Outline Package) type package with 24 pins, referenced by the package suffix 'DBRE4'. It is characterized for operation from -40°C to 85°C, making it reliable for industrial applications that may be subject to harsher temperature environments.

In summary, the SN74LVC828ADBRE4 from Texas Instruments is an ideal solution for designers looking for a low-power, high-speed 10-bit interface register with robust features for easy integration into bus-oriented systems.
