SN74HC32PWT

Inverter Gates Overview

The SN74HC32PWT is a Texas Instruments quadruple 2-input positive-OR gate in the HC logic family. It operates on 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 high-impedance 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 overheat signal combination

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the TSSOP package variant when procuring. Confirm that the component matches the commercial temperature grade (-40°C to +85°C) rather than the military grade (SN54HC32). Ensure compatibility with standard surface-mount assembly processes for the specified package dimensions.

Inverter Gates Selection Notes

Select this component for designs requiring low-power CMOS logic with wide voltage flexibility between 2 V and 6 V. It serves as a direct replacement for older LSTTL OR gates where power consumption is a primary concern. Ensure input signal edge rates meet recommended transition times to prevent oscillations due to the standard CMOS input structure.

Inverter Gates Part Context

This part belongs to the SNx4HC32 series of quadruple 2-input OR gates manufactured by Texas Instruments. The 'SN74' prefix indicates a commercial-grade device, while the 'HC' designation specifies High-speed CMOS technology. The 'PW' suffix identifies the 14-pin Thin Shrink Small Outline Package (TSSOP), which offers a compact footprint suitable for space-constrained printed circuit board layouts.

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?

To ensure optimal performance, the capacitive load at the output should be less than or equal to 70 pF.
