Product Overview: SN74LV8151DGVR

The SN74LV8151DGVR from Texas Instruments is a high-performance, 10-bit universal bus driver designed to operate with a 2.7-V to 3.6-V V_CC supply. It is part of the LV family, which means it has a low-voltage interface and is optimized for low-power consumption while maintaining high-speed operation. This product is particularly suitable for driving bus lines or buffer memory address registers in your digital systems.

Its robust design includes 10-bit drivers, which are divided into two sets of five bits each. The two sections can be used independently or combined to form a single 10-bit section, providing design flexibility. Each section is equipped with its own output-enable (OE) input, which allows for the isolation of the bus lines during power-up or power-down, preventing any unwanted data from being transmitted.

One of the key features of the SN74LV8151DGVR is its support for mixed-mode signal operation. This means that it can receive inputs at 5V TTL levels and translate them to 3.3V CMOS levels, making it an ideal interface between different logic families. It also has a high drive capability, with the ability to source up to 24 mA and sink up to 24 mA, ensuring strong signal integrity even in heavy load conditions.

The device comes in a compact, surface-mount TVSOP (Thin Very Small Outline Package) with 24 pins, designated by the DGVR suffix in its part number. This small footprint makes it an excellent choice for space-constrained applications such as handheld devices, notebooks, and portable communication equipment.

For design protection and operational reliability, the SN74LV8151DGVR incorporates latch-up performance that exceeds 250 mA per JESD 17, and it is specified for ESD protection exceeding JESD 22. These features ensure that the device is resilient against unexpected electrical transients and can withstand harsh operating conditions.

Overall, the SN74LV8151DGVR is a versatile, high-performance bus driver that offers a reliable solution for driving bus lines in a wide range of digital applications. Its compatibility with different logic levels and strong drive capabilities make it a solid choice for designers looking for a dependable and flexible interface component.
