SN74LV132ADBR

Inverter Gates Overview

The SN74LV132ADBR is a quadruple positive-NAND gate with Schmitt-trigger inputs from the Texas Instruments LV series. It operates on a supply voltage (VCC) ranging from 2 V to 5.5 V. The device features a maximum propagation delay (tpd) of 9 ns at 5 V and supports mixed-mode voltage operation on all ports. It includes Ioff support for live insertion and partial power-down modes, along with ESD protection exceeding JESD 22 standards.

Inverter Gates Feature Summary

• Schmitt trigger inputs provide different threshold levels for positive- and negative-going signals to ensure clean jitter-free output.
• Low-drive CMOS design minimizes output ringing, overshoot, and undershoot on signal lines.
• Inputs are overvoltage tolerant, accepting voltages up to 5.5 V regardless of the valid VCC level.

Inverter Gates Applications

• Industrial PC: Rugged PC and Laptop systems
• Access Control and Security: Camera Surveillance IP Network
• Patient Monitoring STB / DVR / Streaming Media

Inverter Gates Procurement Notes

Verify the specific package type matches the required PCB footprint, as the LV132A family is available in SOIC, SSOP, SOP, TSSOP, and TVSOP configurations. Confirm that the ordering suffix corresponds to the desired tape-and-reel quantity or lead finish. Ensure the selected variant meets the required operating temperature range, noting that SN74LV132A supports -40°C to 125°C.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to slow input ramps or noisy environments, as the Schmitt triggers filter out glitches. Choose this part for bus interface applications where minimizing output ringing is necessary. It is suitable for down-voltage translation scenarios because inputs tolerate 5.5 V even at lower supply voltages.

Inverter Gates Part Context

This device belongs to the SNx4LV132A family of quadruple positive-NAND gates with Schmitt-trigger inputs. It is manufactured by Texas Instruments using low-drive CMOS technology. The 'DB' suffix indicates the SSOP-14 package body size. It is part of the broader LV logic series designed for 2-V to 5.5-V operation.

Inverter Gates FAQ

How does the Schmitt trigger function benefit this NAND gate?

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 feature?

Ioff supports live insertion, partial power-down mode, and back drive protection. It ensures that no current flows through the inputs or outputs when the device is powered off or disconnected.
