onsemi 74LVX132M

Overview

74LVX132M from onsemi is a low-voltage quad 2-input NAND Schmitt trigger gate IC operating from 2.0 V to 3.6 V supply, featuring input hysteresis (V_t+ = 2.2 V, V_t− = 0.9 V at V_CC = 3.0 V), 5.5 V-tolerant inputs, and propagation delay as low as 6.1 ns (typ) at 3.3 V with 15 pF load - used in noise-immune signal conditioning for industrial sensor interfaces and mixed-voltage logic level translation.

For engineers reviewing the 74LVX132M datasheet, pinout, applications, or equivalent options, key selection considerations include Schmitt-trigger hysteresis width (0.3–1.2 V), 3.3 V/5 V interface capability, TSSOP-14 WB package thermal and layout constraints, and simultaneous switching noise performance under real-world PCB loading conditions.

Technical Context

The 74LVX132M implements four independent 2-input NAND gates with integrated Schmitt-trigger input thresholds, enabling clean digital edge regeneration from slow-rising or noisy analog-like signals. Its hysteresis (V_H = 0.3–1.2 V) provides immunity to input noise up to ±0.6 V around switching thresholds.

Designed for 3.3 V systems with 5 V-tolerant inputs, it supports bidirectional voltage-level translation without external components. DC input voltage range extends to 5.5 V while V_CC remains within 2.0–3.6 V, and output drive capability is ±4 mA at V_CC = 3.0 V with VOL ≤ 0.36 V and VOH ≥ 2.58 V.

FAQ

What is the maximum input voltage the 74LVX132M can tolerate?

The 74LVX132M supports DC input voltages up to 5.5 V regardless of V_CC level (2.0–3.6 V), enabling safe interfacing with 5 V logic families without external protection. This specification is guaranteed across −40 °C to +85 °C and is validated per the Absolute Maximum Ratings table in the official onsemi datasheet (Rev. 2, April 2024). The 74LVX132M does not require series resistors or clamping diodes for 5 V input compatibility.

Does the 74LVX132M have built-in hysteresis, and what is its typical value?

Yes, the 74LVX132M integrates Schmitt-trigger hysteresis on all inputs, with a typical hysteresis width (V_H) of 0.3 V at V_CC = 3.0 V and up to 1.2 V maximum. Measured as V_t+ − V_t−, this ensures clean output transitions even with slowly changing or noisy inputs. The 74LVX132M's hysteresis is process-guaranteed and tested across temperature and voltage extremes per the DC Electrical Characteristics table.

What is the propagation delay of the 74LVX132M at 3.3 V supply?

At V_CC = 3.3 V ± 0.3 V and CL = 15 pF, the 74LVX132M exhibits a typical propagation delay (t_PLH/t_PHL) of 6.1 ns, with a maximum of 12.5 ns over −40 °C to +85 °C. These values are measured under controlled AC test conditions defined in the onsemi datasheet and reflect worst-case path performance across all four gates. The 74LVX132M maintains consistent delay matching with output skew ≤1.5 ns between channels.

Can unused inputs on the 74LVX132M be left floating?

No - unused inputs on the 74LVX132M must be externally tied HIGH or LOW. Floating inputs may cause increased ICC current, unpredictable output states, or localized heating due to intermediate biasing of internal transistors. The onsemi datasheet explicitly mandates this in the Recommended Operating Conditions note. For the 74LVX132M, connecting unused inputs to V_CC or GND via 10 kΩ resistors is acceptable; direct hard-wiring is preferred for lowest noise sensitivity.

What package type is used for the 74LVX132M, and what are its key mechanical dimensions?

The 74LVX132M is supplied in a TSSOP-14 WB (Wide Body) package, designated Case 948G, with 0.65 mm lead pitch and overall dimensions of 4.90 mm × 4.30 mm × 1.20 mm max height. It features gull-wing leads, Pb-free terminations, and complies with JEDEC MO-153 standards. The 74LVX132M's footprint requires 0.36 mm pad width and 0.70 mm pad length per IPC-7351B recommendations for reliable reflow soldering.
