SN74AUP1G126DSFR Single Bus Buffer Gate with 3-State Outputs

The SN74AUP1G126DSFR is a high-performance, single bus buffer gate featuring three-state outputs from Texas Instruments, designed to operate from 0.8 V to 3.6 V. This makes it ideal for use in low-voltage and low-power applications. The device is part of the advanced ultra-low power (AUP) family, which is renowned for its reduced power consumption without sacrificing speed and performance.

This buffer gate is characterized for operation over the full industrial temperature range (-40°C to 85°C). Its low static power consumption is complemented by its dynamic power consumption, which is minimized by the partial power-down mode feature. This feature significantly reduces power consumption by disabling the outputs, allowing the input to remain active.

The SN74AUP1G126DSFR is offered in a small form factor package, the SOT-5X3 DSBGA, which is suitable for space-constrained applications. Its small size, combined with the low-power design, makes it an excellent choice for portable and battery-powered devices where power efficiency and size are critical considerations.

Key features of the SN74AUP1G126DSFR include:

• Low Static-Power Consumption: This device has a very low ICC of 0.9 µA maximum.
• Low Dynamic-Power Consumption: At VCC = 3.6 V, the typical power consumption is only 0.9 µA/MHz.
• Low Input Capacitance: The device has an input capacitance of 1.5 pF (typical), which is less than the typical input capacitance of devices in the standard AUP family.
• Partial Power-Down Mode Operation: The partial power-down mode allows the input circuit to be operational while the output is in the high-impedance state, reducing power consumption significantly.
• Wide Operating Voltage Range: The device can operate across a wide voltage range, accommodating various application needs.

With its three-state output, the SN74AUP1G126DSFR is able to drive the bus lines in a high-impedance state during power down or inactive periods, thereby preventing any damaging backflow of current. This feature makes it a versatile component for bus management in complex digital systems.

Whether you are designing consumer electronics, portable devices, or industrial control systems, the SN74AUP1G126DSFR offers a reliable and efficient solution for your buffering needs.
