SN74LV132ADRE4

Inverter Gates Overview

The SN74LV132ADRE4 is a quadruple positive-NAND gate with Schmitt-trigger inputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features low drive capability to minimize output ringing. The device supports mixed-mode voltage operation on all ports, allowing inputs to accept voltages up to 5.5 V regardless of the valid VCC level. It includes Ioff support for live insertion and partial power-down modes. The component is housed in a 14-pin SOIC package.

Inverter Gates Feature Summary

• Schmitt trigger inputs provide different threshold levels for positive- and negative-going signals to ensure clean jitter-free outputs from slow input ramps.
• Low drive design reduces output signal ringing and minimizes overshoot and undershoot on bus interfaces.
• Ioff feature enables live insertion, partial power-down mode, and back drive protection.

Inverter Gates Applications

• Industrial PC: Rugged PC and Laptop
• Access Control and Security: Camera Surveillance IP Network
• Vending, Payment and Change Machines

Inverter Gates Procurement Notes

Verify the specific ordering suffix 'E4' corresponds to the lead-free and RoHS-compliant variant as defined in the manufacturer's documentation. Confirm that the SOIC (D) package designation matches the required footprint for the target PCB layout. Ensure compatibility with the specified operating temperature range of -40°C to 125°C for the intended environment.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt trigger inputs. It is suitable for applications requiring down-voltage translation where inputs tolerate 5.5 V while the system operates at lower voltages. Consider the low-drive characteristic if minimizing signal ringing on long traces or bus interfaces is a priority over high-speed switching performance.

Inverter Gates Part Context

This part belongs to the SNx4LV132A family of quadruple positive-NAND gates. The LV series is designed for 2-V to 5.5-V VCC operation using CMOS technology. The 'E4' suffix typically indicates environmental compliance, specifically lead-free and RoHS status, distinguishing it from standard commercial variants.

Inverter Gates FAQ

How does the Schmitt trigger functionality benefit signal integrity?

The Schmitt trigger provides different input threshold levels for positive- and negative-going signals. This allows the circuit to be triggered from slow input ramps while still producing clean, jitter-free output signals.

What is the purpose of the Ioff support feature?

Ioff support allows the device to enter a partial power-down mode. This protects against back drive currents and supports live insertion into powered systems without damaging the component.
