SN74LV05ADR

Inverter Gates Overview

The SN74LV05ADR is a hex inverter integrated circuit from Texas Instruments, belonging to the LV (Low-Voltage CMOS) logic series. It features six independent inverters with open-drain outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V and supports input logic levels compatible with standard TTL thresholds. Key electrical characteristics include a maximum quiescent current of 20 µA and output drive capabilities of 12 mA for both high and low states. It functions reliably across an extended temperature range from -40°C to +125°C.

Inverter Gates Procurement Notes

Verify the complete part number including the suffix 'ADR' to ensure the correct tape-and-reel packaging variant is ordered. Confirm that the application design accommodates the open-drain output nature, which requires external pull-up resistors for proper high-state operation. Ensure supply voltage constraints remain within the specified 2 V to 5.5 V range to maintain device integrity and logical functionality.

Inverter Gates Selection Notes

Select this component when a compact hex inverter solution with open-drain outputs is required for low-voltage digital designs. It is appropriate for systems needing wide voltage tolerance and low static power consumption. Consider the SOIC-14 package size for PCB layout constraints. Verify that the load conditions and pull-up resistor values align with the 12 mA output current capability and desired switching speeds.

Inverter Gates Part Context

This device is part of the SN74LVxxA family of low-voltage CMOS logic devices from Texas Instruments. The LV series is designed to bridge the gap between traditional 5 V TTL logic and modern lower voltage standards. The SN74LV05A specifically provides hex inverters, offering a cost-effective and space-efficient alternative to discrete transistor solutions for basic inversion tasks in mixed-voltage environments.

Inverter Gates FAQ

Why are external pull-up resistors required with the SN74LV05ADR?

The SN74LV05ADR features open-drain outputs, meaning it can only actively pull the output line to ground (logic low). It cannot actively drive the line high; therefore, external pull-up resistors are necessary to establish the high logic state.

What is the maximum output current capability of this device?

The datasheet specifies a maximum output current of 12 mA for both sourcing (high state via pull-up) and sinking (low state) operations.
