SN74HCT14PWT

Inverter Gates Overview

The SN74HCT14PWT is a hex inverter integrated circuit manufactured by Texas Instruments, featuring Schmitt trigger inputs for noise filtering. It operates within a supply voltage range of 4.5V to 5.5V and utilizes a 14-TSSOP surface-mount package. The device contains six independent inverting circuits with one input per channel. Key electrical specifications include a maximum static current of 2 µA, output drive capabilities of 4mA for both high and low states, and a maximum propagation delay of 30ns at 5.5V with a 50pF load. It supports logic levels of 0.5V to 0.6V for low and 1.9V to 2.1V for high, operating across a temperature range of -40°C to 85°C.

Inverter Gates Feature Summary

• Integrates Schmitt trigger functionality on all inputs to provide hysteresis and improved noise immunity for signal conditioning applications.

Inverter Gates Applications

• Signal waveform shaping and conversion from noisy analog-like signals to clean digital logic levels.
• Oscillator circuits requiring precise threshold control and stable frequency generation.
• Timing pulse generation where clean transitions are critical for accurate clocking.

Inverter Gates Procurement Notes

Verify component authenticity through authorized channels due to the part's end-of-life status. Confirm RoHS3 compliance and MSL rating during procurement. Check for specific ordering suffixes that may indicate tape-and-reel or cut-tape packaging variations. Ensure compatibility with existing PCB footprints for the 14-TSSOP package before finalizing orders.

Inverter Gates Selection Notes

Select this component when HCT logic compatibility with TTL inputs is required alongside Schmitt trigger noise rejection. The 14-TSSOP package offers space efficiency for surface-mount designs. Consider the 4.5V to 5.5V supply constraint and ensure the application environment remains within the specified -40°C to 85°C operational temperature range.

Inverter Gates Part Context

This component belongs to the SN74HCT series, which provides CMOS density with TTL-compatible inputs. The '14' designation specifically indicates a hex inverter configuration. The 'PWT' suffix denotes the 14-lead Thin-Shrink Small Outline Package (TSSOP) with a 0.173-inch width. This series is designed for general-purpose digital logic applications requiring robust switching characteristics.
