SN74LV8T245PWR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LV8T245 is an octal bus transceiver with 3-state outputs and logic level shifting capabilities. It operates on a single supply voltage ranging from 1.6 V to 5.5 V. The device supports up-translation for lower voltage CMOS inputs, such as 1.2 V to 1.8 V or 1.8 V to 3.3 V, and down-translation using 5.5 V tolerant input pins. It achieves data rates of up to 150 Mbps at 5 V or 3.3 V supplies. Latch-up performance exceeds 250 mA per JESD 17 standards.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Supports bidirectional data translation between different voltage domains
• Features enhanced input thresholds for low-voltage signal up-translation
• Includes 5.5 V tolerant inputs for high-voltage signal down-translation
• Provides balanced CMOS 3-state outputs controlled by direction and enable pins

Buffers, Drivers, Receivers, Transceivers Applications

• Enabling or disabling digital signals in system control
• Eliminating slow or noisy input signals
• Holding signals during controller reset sequences
• Switch debounce applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix against the datasheet orderable addendum to ensure correct physical dimensions and pinout compatibility. Confirm that the selected variant meets the required thermal resistance and operating temperature range specifications for the target environment before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between systems requiring both up-translation and down-translation across multiple voltage levels. Ensure the application does not exceed the 150 Mbps data rate limit at higher supply voltages. Verify that input transition rates comply with the specified limits to prevent excessive power consumption.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to Texas Instruments' LVxT family of logic devices designed for integrated voltage level translation. It provides a solution for connecting components operating at various standard CMOS levels, including 1.8 V, 2.5 V, 3.3 V, and 5 V, within a single octal transceiver architecture.
