SN74HC7032DT

Inverter Gates Overview

The SN74HC7032DT is a Texas Instruments quadruple 2-input positive OR gate featuring Schmitt-trigger inputs, housed in a 14-pin SOIC package. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature from -40°C to 85°C. The device provides balanced CMOS push-pull outputs capable of driving up to 10 LSTTL loads with ±4 mA drive at 5 V. Propagation delay ranges from 14 ns to 28 ns depending on voltage, while transition times vary between 6 ns and 16 ns.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for tolerance against slow or noisy input signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Low power consumption with maximum ICC of 20 µA
• Capable of driving up to 10 LSTTL loads

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Directly controlling fan driver enable pins via combined overheat signals

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the tape and reel packaging format rather than tube packaging. Confirm that the moisture sensitivity level (MSL) rating of Level-1 aligns with your assembly process requirements. Ensure the lead finish NIPDAU meets your solderability standards. Cross-reference the RoHS compliance status with current environmental regulations applicable to your region before finalizing procurement.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for applications requiring wide voltage operation between 2 V and 6 V. Consider the propagation delay specifications if timing constraints are tight. Verify that the output drive capability meets the load requirements, particularly regarding capacitive loading limits to maintain signal integrity.

Inverter Gates Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices manufactured by Texas Instruments. It is functionally related to standard OR gates but distinguished by the inclusion of Schmitt triggers on all inputs. The device is part of a broader family including variants like SN74HC32, which lacks the Schmitt-trigger feature. It serves as a fundamental building block for digital logic circuits requiring robust signal conditioning.
