SN74HC32PWR

Inverter Gates Overview

The SN74HC32PWR is a quadruple 2-input OR gate manufactured by Texas Instruments in the HC logic series. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. The device features buffered inputs, balanced CMOS push-pull outputs, and standard CMOS input characteristics. It provides significant power reduction compared to LSTTL logic ICs and supports fanout up to 10 LSTTL loads.

Inverter Gates Feature Summary

• Contains four independent 2-input OR gates performing Boolean function Y = A + B
• Balanced CMOS push-pull outputs allow similar sourcing and sinking currents
• Standard CMOS inputs are high impedance with clamping diode structures

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 package type matches the design requirements, as the SN74HC32 family includes SOIC, SSOP, PDIP, SO, TSSOP, CDIP, CFP, and LCCC options. Confirm that the ordering suffix corresponds to the desired packaging format and ensure compliance with RoHS standards for the intended application environment.

Inverter Gates Selection Notes

Select this component when a wide operating voltage range between 2 V and 6 V is required. It is suitable for designs needing low power consumption relative to LSTTL while maintaining compatibility with standard CMOS logic levels. Ensure input signal edge rates meet recommended transition times to prevent oscillations.

Inverter Gates Part Context

This part belongs to the SNx4HC32 family of quadruple 2-input OR gates. The 'P' suffix indicates the TSSOP (14-pin) package variant. Other variants include SN74HC32D (SOIC), SN74HC32DB (SSOP), SN74HC32N (PDIP), and SN74HC32NS (SO).

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be terminated to either VCC or ground to prevent undefined operational states.

What is the maximum capacitive load recommended?

The datasheet recommends ensuring the capacitive load at the output is less than or equal to 70 pF for optimal performance.
