SN74LVC07ANSR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC07A is a hex buffer and driver featuring open-drain outputs, designed for VCC operation from 1.65 V to 5.5 V. Inputs and outputs accept voltages up to 5.5 V, enabling voltage translation between different logic levels. The device supports Ioff functionality for partial-power-down mode and back-drive protection. It operates within a temperature range of -40°C to +125°C. Propagation delay (tpd) ranges from 1 ns to 6.1 ns depending on supply voltage and temperature. Maximum low-level output current (IOL) reaches 24 mA at 3 V.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package type against the orderable addendum in the datasheet, as the SN suffix indicates an SOIC package variant. Confirm that the required operating voltage falls within the 1.65 V to 5.5 V range. Ensure input signals do not exceed 5.5 V to prevent damage. Check thermal requirements if operating near the maximum junction temperature limit.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-drain output capability is required for bus sharing or level shifting. It is suitable for translating signals between 1.8-V, 2.5-V, 3.3-V, and 5-V logic families. Consider the 24 mA drive current for driving multiple inputs or LEDs. Verify that the application does not require push-pull outputs, as this device only provides open-drain functionality.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74LVC07A family of hex buffers with open-drain outputs. It is part of the broader LVC logic series, which offers wide voltage operation and high speed. The device is manufactured using CMOS technology, providing balanced output drive and low power consumption compared to older logic families.

Buffers, Drivers, Receivers, Transceivers FAQ

Can the SN74LVC07A be used for voltage translation?

Yes, the inputs and outputs accept voltages up to 5.5 V, allowing the device to translate signals between different voltage domains such as 1.8 V, 2.5 V, 3.3 V, and 5 V.

What is the purpose of the Ioff feature?

The Ioff feature disables the outputs when VCC is 0 V, preventing damaging current backflow through the device. This supports live insertion and partial-power-down modes.
