onsemi MC74LVX132DTG

Overview

MC74LVX132DTG from onsemi is a quad 2-input NAND Schmitt trigger IC in TSSOP-14 package, designed for noise-immune digital signal conditioning in mixed-voltage systems. It operates from 2.0 V to 3.6 V, delivers 5.8 ns typical propagation delay at 3.3 V, tolerates input voltages up to 6.5 V, and provides hysteresis of 0.30–1.60 V depending on supply. It is used in industrial sensor interface circuits where slow-rising or noisy signals require clean logic-level conversion.

For engineers reviewing the MC74LVX132DTG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping, confirmed Schmitt-trigger thresholds (VT+ = 1.15–2.60 V, VT− = 0.30–1.90 V), real-world noise immunity metrics (VOLP ≤ 0.5 V), and two documented alternative parts with precise technical and application differences.

Technical Context

The MC74LVX132DTG implements four independent Schmitt-trigger NAND gates using silicon gate CMOS technology. Each gate features asymmetric input hysteresis (ΔVT = VH = 0.30–1.60 V) to reject noise on slow-transitioning signals, and internal buffering ensures high noise immunity and stable output drive.

Its inputs are overvoltage tolerant up to 6.5 V, enabling direct interfacing between 3.0 V logic domains and legacy 5.0 V systems without level shifters. The device supports operation from −40 °C to +125 °C and exhibits latchup immunity exceeding ±300 mA per IEC/JEDEC standards.

FAQ

What is the maximum input voltage rating for MC74LVX132DTG?

The MC74LVX132DTG supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This overvoltage tolerance allows direct connection to 5.0 V signal sources while operating from a 3.3 V supply - eliminating external level-shifting components in mixed-voltage designs. The specification is validated per Absolute Maximum Ratings table in the official onsemi datasheet.

Does MC74LVX132DTG support operation at 2.5 V supply?

Yes, MC74LVX132DTG is fully specified for operation at 2.0 V to 3.6 V, including 2.5 V. At VCC = 2.5 V, the typical propagation delay increases to ~8.3 ns (CL = 15 pF), VT+ is 1.31 V, and VT− is 0.64 V - all guaranteed across −40 °C to +125 °C per Recommended Operating Conditions and DC Electrical Characteristics tables.

What is the hysteresis voltage (VH) of MC74LVX132DTG at 3.3 V supply?

At VCC = 3.3 V, the MC74LVX132DTG exhibits a typical hysteresis voltage (VH) of 0.76 V, calculated as VT+ (1.82 V) minus VT− (1.06 V). The datasheet specifies VH ranging from 0.30 V (min) to 1.50 V (max) across temperature and process variation - ensuring consistent noise rejection in real-world industrial deployments.

Is MC74LVX132DTG pin-compatible with standard 74LVX00 logic devices?

Yes, MC74LVX132DTG has identical pin configuration and function to MC74LVX00, but with Schmitt-trigger inputs instead of standard CMOS inputs. Pin 1 (A1), Pin 2 (B1), Pin 3 (Y1), etc., match exactly - allowing drop-in replacement where hysteresis is needed without PCB redesign. This compatibility is explicitly stated in the datasheet's first paragraph and confirmed in Figure 1 and PIN ASSIGNMENT.

What package type is used for MC74LVX132DTG?

MC74LVX132DTG uses the TSSOP-14 (Thin Shrink Small Outline Package) with case number 948G, measuring 4.9 mm × 4.4 mm × 1.2 mm and featuring 0.65 mm lead pitch. It is Pb-free and RoHS compliant, with marking "LVX132" and date code per onsemi's generic marking diagram on page 6 of the datasheet.
