SN74HCT14DBR

Inverter Gates Overview

The SN74HCT14DBR is a hex Schmitt-trigger inverter manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features six independent inverting channels with Schmitt-trigger inputs for noise filtering. The device utilizes CMOS logic technology and is housed in a 14-pin SOIC surface-mount package. Key electrical characteristics include a maximum propagation delay of 38 ns, output currents of ±4 mA, and an operating temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Hex Schmitt-trigger inverters provide hysteresis for effective noise filtering on input signals
• CMOS logic technology ensures low static power consumption during operation
• Standard TTL-compatible input thresholds facilitate direct interfacing with TTL-driven systems

Inverter Gates Applications

• Signal conditioning and waveform shaping for noisy digital environments
• Pulse generation and timing circuits requiring precise threshold control
• Level shifting between TTL and CMOS logic domains

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SOIC-14 package and tape-and-reel shipping configuration. Confirm that the HCT logic family aligns with the system's 5V supply requirements and TTL input compatibility needs. Ensure the component meets RoHS compliance standards as indicated in official documentation before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when TTL-compatible input levels are required alongside the noise immunity provided by Schmitt triggers. The HCT series is appropriate for designs strictly operating at 5V, unlike HC variants which support wider voltage ranges. Consider the SOIC-14 package dimensions for PCB layout constraints and verify thermal performance within the specified industrial temperature range.

Inverter Gates Part Context

This part belongs to the SN74HCTxx series of high-speed CMOS logic devices produced by Texas Instruments. The HCT family is specifically engineered to maintain pinout and functional compatibility with legacy TTL logic while offering the lower power consumption advantages of modern CMOS technology. It serves as a standard solution for mixed-logic system integration.

Inverter Gates Replacement Considerations

SN74HCT14DR: Identical function and package from Texas Instruments with alternative reel packaging. SN74HCT14D: Same manufacturer and logic family but typically supplied in cut-tape or tube formats rather than tape-and-reel.
