Product details
Overview
74LV132AS14-13 from Diodes Incorporated is a quad 2-input NAND gate IC with Schmitt-trigger inputs, designed for noise-immune digital signal conditioning in mixed-voltage systems. It operates from 2.0V to 5.5V, supports IOFF partial power-down, tolerates 5.5V inputs, and delivers ±12mA output drive at 4.5V - used in PC peripheral interface logic and voltage translation circuits.
For engineers reviewing the 74LV132AS14-13 datasheet, 74LV132AS14-13 pinout, 74LV132AS14-13 application, or 74LV132AS14-13 equivalent, key selection criteria include Schmitt-trigger hysteresis (0.5–2.0V), propagation delay (3.9–18.5ns), IOFF leakage (<5μA), 5.5V-tolerant inputs, and SO-14 package compatibility with legacy 74-series footprints.
Technical Context
This device implements four independent NAND gates, each with hysteresis-enabled Schmitt-trigger inputs to reject noise on slow or noisy signals - critical for reset, enable, and clock conditioning paths. The IOFF circuit disables outputs during power-down to prevent back-current, enabling hot-swap and partial-power-down system architectures.
Input voltage tolerance up to 5.5V allows interfacing between 3.3V logic and 5V peripherals without level shifters. Propagation delay varies with supply (e.g., 3.9ns typ. at 5.0V, 7.9ns at 2.5V) and load (15pF/50pF), supporting both low-power and timing-critical applications across industrial temperature ranges (–40°C to +125°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with Schmitt-trigger inputs |
| Supply Voltage Range | 2.0V to 5.5V - enables single-rail operation across 2.5V, 3.3V, and 5V systems |
| Hysteresis (VT+ − VT−) | 0.5V min at 5.0V - rejects >500mV noise spikes on input signals |
| Output Drive | ±12mA at VCC = 4.5V - directly drives LEDs, small capacitive loads, or TTL inputs |
| IOFF Leakage | <5μA - prevents current backflow when VCC = 0V, essential for bus isolation |
| Propagation Delay | 3.9ns typ. at 5.0V/15pF - supports >100MHz toggle rates in clean signal environments |
| Input Voltage Tolerance | 0V to 5.5V - allows 3.3V logic to safely interface with 5V sensors or legacy peripherals |
Pinout & Package
74LV132AS14-13 is supplied in a 14-pin SOIC (SO-14) package with standard 1.27mm pitch, 8.74mm body width, and 3.99mm width - compatible with JEDEC MS-012AC footprint and automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | Schmitt-trigger input; accepts 0–5.5V, enables noise-immune signal acquisition |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Schmitt-trigger input; independently conditioned per gate pair |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Push-pull CMOS output; sinks/sources up to 12mA, rail-to-rail swing |

Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides 0.5–2.0V hysteresis to eliminate chatter on slow-rising signals (e.g., mechanical switch debouncing) |
| IOFF partial power-down | Disables outputs when VCC = 0V, preventing back-current into powered subsystems during hot-plug events |
| 5.5V-tolerant I/O | Allows direct connection to 5V buses while operating from 3.3V supply - eliminates external level translators |
| Low dynamic power | 7.5pF typical power dissipation capacitance at 3.3V/10MHz - reduces switching current and EMI |
Applications
| PC Peripheral Interface | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Isolating USB hub reset lines and managing hot-swap detection in notebook docking stations. IC Role / Device Role / Timing Role: NAND gate with Schmitt-trigger input acts as noise-filtered enable latch for USB PHY power sequencing. Use Value: Hysteresis rejects ESD-induced transients on unshielded cables; IOFF prevents backfeed during partial system sleep states. | Use Scenario: Debouncing mechanical limit switches and converting slow analog sensor outputs (e.g., thermistor comparators) into clean digital logic levels. IC Role / Device Role / Timing Role: Input conditioner that converts noisy, slow-rising switch closures into monotonic logic transitions. Use Value: 0.5V minimum hysteresis ensures reliable edge detection even with >100mV of conducted noise on factory floor wiring. |
| Legacy 5V System Integration | Power-Down Signal Isolation |
Use Scenario: Interfacing modern 3.3V microcontrollers with legacy 5V display controllers or EEPROMs in set-top boxes. IC Role / Device Role / Timing Role: Level-translating NAND gate enabling bidirectional control signaling without external translators. Use Value: 5.5V-tolerant inputs accept 5V logic highs while operating from 3.3V supply - reduces BOM count and board space. | Use Scenario: Controlling power-enable signals to downstream modules (e.g., Wi-Fi radios) during system suspend/resume cycles. IC Role / Device Role / Timing Role: Gate isolating control path between always-on PMIC and domain-specific power rails. Use Value: IOFF functionality blocks reverse current flow when module VCC is off, eliminating risk of latch-up or supply contention. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate with Schmitt-trigger input applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV2G132DCUR | Dual-gate configuration (2 gates), smaller X2SON-8 package, lower max supply (5.5V same), identical hysteresis spec | Targeted for space-constrained portable designs requiring only two NAND functions | Select when board area is critical and full quad functionality is unnecessary |
| 74LVC132PW,118 | TSSOP-14 package, same logic function, but lacks IOFF; max input tolerance 5.5V, hysteresis slightly lower (0.45V min at 3.3V) | Used where partial power-down is not required and cost-per-gate is prioritized | Choose when IOFF is not needed and TSSOP footprint is preferred over SOIC |
Compared with SN74LV2G132DCUR and 74LVC132PW,118, the 74LV132AS14-13 uniquely combines quad gate density, SO-14 compatibility, full IOFF support, and guaranteed 0.5V hysteresis at 5V - making it optimal for industrial control and legacy system upgrades requiring robust noise immunity and power-domain isolation.

FAQ
What is the maximum input voltage the 74LV132AS14-13 can tolerate?
The 74LV132AS14-13 accepts input voltages from –0.5V to 5.5V regardless of VCC level, enabling safe interfacing with 5V signals while operating from a 3.3V or 2.5V supply. This tolerance is specified under absolute maximum ratings and applies to all inputs (1A–4B), verified per DS35706 Rev. 1–2 Section "Absolute Maximum Ratings".
Does the 74LV132AS14-13 support partial power-down operation?
Yes - the device integrates an IOFF circuit that automatically disables all outputs when VCC is at 0V, preventing damaging back-current flow from powered I/O lines into the unpowered IC. This feature is fully characterized per JESD78 Class I latch-up testing and confirmed in the "Recommended Operating Conditions" table of DS35706.
What is the typical hysteresis voltage at 3.3V supply?
At VCC = 3.3V, the typical hysteresis (VT+ − VT−) is 0.825V, with a guaranteed minimum of 0.33V and maximum of 1.32V across temperature (–40°C to +125°C). These values are measured per the Electrical Characteristics table in DS35706, ensuring reliable noise rejection in industrial environments.
Can the 74LV132AS14-13 drive a 50pF capacitive load at 10MHz?
Yes - the device specifies switching characteristics at CL = 50pF, with propagation delay of 5.3–11ns at 5.0V and 7.6–17.5ns at 3.3V. Its typical power dissipation capacitance is 7.5pF at 3.3V/10MHz, confirming stable operation into 50pF loads with adequate timing margin for most digital interfaces.
