SN74ALVTH16827 20-Bit Universal Bus Driver with 3-State Outputs

The SN74ALVTH16827 from Texas Instruments is a high-performance, 20-bit universal bus driver designed with two distinct banks of ten bits each. Each bank is equipped with 3-state outputs, making this device ideal for driving bus lines or buffer memory address registers. This product belongs to the ALVTH family, which is known for its low-voltage, high-speed operation.

The SN74ALVTH16827 operates with a 2.5 V to 3.6 V V_CC supply range, providing a high degree of flexibility for various system voltage requirements. It features a -40°C to 85°C operating temperature range, ensuring reliability across diverse working conditions. This device boasts edge-rate control circuitry that significantly reduces noise generation, a critical feature for maintaining signal integrity in high-speed applications.

Each bank of the SN74ALVTH16827 can be operated independently, with the control functions being enabled by separate output-enable (OE) inputs for each bank. When OE is high, the outputs are in the high-impedance state, which is essential for bidirectional data flow in multiplexed bus applications.

The device's inputs are LVTTL-compatible, which allows for easy interfacing with a variety of logic levels. Additionally, the SN74ALVTH16827 supports bus-hold data inputs that eliminate the need for external pull-up resistors, simplifying board design and reducing overall component count.

Texas Instruments ensures that the SN74ALVTH16827 adheres to the stringent standards for which they are known, providing robust performance and reliability. This particular device is packaged in a 56-pin thin shrink small-outline package (TSSOP), offering a compact footprint suitable for space-constrained applications.

In summary, the SN74ALVTH16827 is a versatile, high-speed bus driver that provides designers with the performance and features needed for efficient and reliable data transmission in advanced digital systems. Its robust construction and noise-reducing capabilities make it an excellent choice for a wide range of industrial, computing, and telecommunications applications.
