MC74ACT132DG

Inverter Gates Overview

The MC74ACT132DG is a high-performance silicon-gate CMOS quad 2-input NAND Schmitt trigger manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides outputs capable of sourcing and sinking 24 mA. Propagation delay is specified at a maximum of 13.0 ns for low-to-high transitions and 12.5 ns for high-to-low transitions at 5.0 V with a 50 pF load, measured across an operating temperature range of -40°C to +85°C.

Inverter Gates Feature Summary

• Schmitt trigger inputs utilize positive feedback to speed up slow input transitions and provide distinct threshold voltages for rising and falling signals.
• Outputs are designed to source and sink 24 mA of current.
• The ACT logic series ensures compatibility with TTL input levels.

Inverter Gates Applications

• Signal conditioning for slowly changing waveforms
• Noise filtering in digital circuits
• Jitter-free output signal generation

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DG' corresponds to the SOIC-14 package and Pb-Free status as defined in the manufacturer's documentation. Confirm that the required logic family (ACT) matches the system design requirements regarding voltage levels and input compatibility before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside Schmitt trigger functionality. Ensure the application operates within the 4.5 V to 5.5 V supply range. Consider the 24 mA drive capability if interfacing with loads requiring higher current than standard CMOS outputs provide.

Inverter Gates Part Context

This part belongs to the MC74AC/74ACT132 series, which contains four independent 2-input NAND gates. The 'ACT' designation indicates the use of Advanced CMOS technology optimized for 5 V operation with TTL input thresholds, distinguishing it from the broader voltage range AC series.

Inverter Gates Replacement Considerations

MC74ACT132D is listed as a direct replacement option.

Inverter Gates FAQ

How does the Schmitt trigger function improve signal integrity?

It uses positive feedback to effectively speed up slow input transitions and provides different input threshold voltages for positive and negative-going transitions, resulting in sharply defined, jitter-free output signals.

What is the hysteresis characteristic of the MC74ACT132DG?

The hysteresis between the positive-going and negative-going input thresholds is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
