SN74HC7032N

Inverter Gates Overview

The SN74HC7032N is a quadruple 2-input OR gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and features balanced CMOS push-pull outputs capable of driving up to 10 LSTTL loads. The device provides low power consumption with a maximum ICC of 20 µA and low input current of 1 µA. Propagation delay ranges from 14 ns at 6 V to 163 ns at 2 V, while transition times vary between 6 ns and 95 ns depending on voltage. It utilizes a 14-pin PDIP package measuring 19.30 mm by 6.40 mm.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide hysteresis for tolerance against slow or noisy signals
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Low static power consumption with minimal supply current requirements

Inverter Gates Applications

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

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'N' corresponds to the 14-pin Plastic Dual In-Line Package (PDIP) as defined in the official datasheet. Confirm that the component status is listed as Active Production. Ensure the selected variant meets the required operating temperature range of -40°C to 85°C for your application environment.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for designs requiring a wide supply voltage range from 2 V to 6 V. Consider the 14-pin PDIP form factor if through-hole mounting is necessary for the target PCB layout.

Inverter Gates Part Context

This device belongs to the SN74HC series of high-speed CMOS logic gates. It implements the Boolean function Y = A + B across four independent channels. The SN74HC7032N specifically denotes the PDIP package version, distinct from the SOIC variants like the SN74HC7032D.

Inverter Gates FAQ

How does the Schmitt-trigger input benefit signal processing?

The Schmitt-trigger architecture introduces hysteresis, making the device tolerant to slow input transitions and noisy signals without requiring strict input transition rate specifications.

What are the limits for unused inputs?

Unused inputs must not be left floating; they should be terminated to either VCC or ground to prevent undefined operational states and excessive dynamic current consumption.
