SN74LS19ADBR

Inverter Gates Overview

The SN74LS19ADBR is a Schmitt-trigger NAND gate and inverter integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic series, featuring six independent channels within a single package. The device utilizes a 16-pin SOIC surface-mount package. It operates with a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from 0°C to +70°C. Key electrical characteristics include a propagation delay of 19 ns and a low-level output current capability of 8 mA.

Inverter Gates Feature Summary

• Integrates Schmitt-trigger functionality for noise immunity on NAND gates and inverters
• Provides six independent logic channels in a compact surface-mount package
• Compatible with standard TTL logic families for system integration

Inverter Gates Applications

• Signal conditioning for noisy digital environments
• Waveform shaping and pulse generation circuits
• Basic logic gating in industrial control systems

Inverter Gates Procurement Notes

Verify the specific suffix 'DBR' indicates the tape-and-reel packaging format rather than tube packaging. Confirm RoHS compliance status through official documentation as manufacturing practices may vary. Ensure the supplier provides valid traceability for this discontinued or legacy component type.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger input hysteresis is required to prevent false triggering from slow-rising signals. Compare against non-Schmitt variants like the SN74LS00 if noise immunity is not a primary design constraint. Verify that the 16-pin SOIC footprint matches the target PCB layout constraints.

Inverter Gates Part Context

This part is part of the broader 74LS family of high-speed TTL logic devices. It serves as a specialized variant combining NAND and inverter functions with Schmitt-trigger inputs. It is distinct from standard logic gates lacking hysteresis, offering improved performance in high-noise applications common in older industrial designs.

Inverter Gates Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74LS19DR. Verify functional equivalence regarding Schmitt-trigger thresholds and output drive capabilities before substitution.
