SN74HC32DBR

Inverter Gates Overview

The SN74HC32DBR is a quadruple 2-input positive-OR gate manufactured by Texas Instruments in the HC logic family. 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 clamp diode structures. 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 with high impedance and internal clamping diodes

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Creating multi-input OR functions by combining multiple gates

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SSOP package and tape-and-reel carrier configuration. Confirm RoHS compliance and lead finish specifications match project requirements. Ensure the component status remains Active Production before finalizing procurement plans.

Inverter Gates Selection Notes

Select this component for designs requiring wide voltage operation between 2 V and 6 V. It is suitable for applications needing low power consumption relative to LSTTL alternatives. Verify that input signal edge rates meet recommended transition times to prevent excessive current consumption or oscillations.

Inverter Gates Part Context

This part belongs to the SNx4HC32 series of quadruple 2-input OR gates. It utilizes the SSOP (DB) package variant, which measures approximately 6.50 mm by 5.30 mm.

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.
