Product details
Overview
74LV32AS14-13 from Diodes Incorporated is a quad 2-input OR gate IC in SO-14 package, operating from 2.0V to 5.5V supply, delivering 12mA output drive at 4.5V, with 5.5V-tolerant inputs and IOFF partial power-down protection-used for logic-level translation and signal isolation in mixed-voltage embedded control systems.
For engineers reviewing the 74LV32AS14-13 datasheet, 74LV32AS14-13 pinout, 74LV32AS14-13 application, or 74LV32AS14-13 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF-enabled power-down safety, propagation delay ≤5.5ns at 5V, Schmitt-trigger inputs for noise immunity, and SO-14 thermal and routing compatibility.
Technical Context
This device implements four independent non-inverting OR logic functions (Y = A + B) using CMOS technology, with Schmitt-trigger inputs enabling robust noise rejection on slow or noisy signals. Each gate supports rail-to-rail input voltage range up to 5.5V independent of VCC, allowing interoperability between 3.3V and 5V domains.
The IOFF circuit actively disables outputs during power-down, preventing back-current flow when VCC = 0V-critical for hot-swap and partial-power-down architectures. Propagation delay is load- and voltage-dependent, specified down to 3.6ns (typ) at 5.0V/CL=15pF, with guaranteed max 6.5ns across -40°C to +125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input OR gates (Y = A + B) |
| Supply Voltage Range | 2.0V to 5.5V - enables single-supply operation across 2.5V, 3.3V, and 5V systems |
| Input Voltage Tolerance | Up to 5.5V - allows 5V inputs into 3.3V-powered system without level shifters |
| IOFF Leakage Current | ≤5 μA at VCC = 0V - prevents backflow damage during partial power-down |
| Output Drive Strength | ±12mA at VCC = 4.5V - sufficient to drive standard TTL loads or multiple CMOS inputs |
| Propagation Delay | ≤6.5ns max at 5.0V/CL=15pF - supports >100MHz toggle rates in clean signal paths |
| Input Hysteresis | Schmitt-trigger action - provides ≥0.5V hysteresis for reliable switching on slow edges |
Pinout & Package
74LV32AS14-13 is housed in a 14-pin Small Outline (SO-14) package with standard 1.27mm pitch, 8.53–8.74mm body width, and 1.47–1.73mm height-compatible with IPC-7351B SOIC-14 footprint and reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | Active-high logic input; 5.5V tolerant; Schmitt-triggered |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Active-high logic input; 5.5V tolerant; Schmitt-triggered |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Push-pull CMOS output; IOFF active when VCC = 0V |
| 7 | GND | Ground reference for all logic and power domains |
| 14 | VCC | Primary power supply (2.0–5.5V); powers internal logic and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 2.0V–5.5V operation eliminates need for separate voltage rails in multi-supply systems |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0V, blocking current backflow in live-backplane designs |
| Voltage translation capability | 5.5V-tolerant inputs accept 3.3V or 5V signals while powered from 2.7V–3.6V supplies |
| Schmitt-trigger inputs | ≥0.5V hysteresis rejects noise on slow-rising control lines (e.g., reset, enable, status flags) |
| Low dynamic power | 20μA ICC at 5.5V - reduces quiescent current in battery-backed or always-on subsystems |
Applications
| Industrial Control I/O Expansion | USB Hub Power Management |
|---|---|
|
Use Scenario: OR-ing enable signals from multiple microcontrollers to activate shared peripherals in PLC backplanes. IC Role / Device Role / Timing Role: Logic-level combiner for redundant enable paths; no timing-critical path-propagation delay irrelevant. Use Value: Eliminates discrete diode-OR networks, reducing board space and forward-voltage drop errors. |
Use Scenario: Combining over-current fault signals from USB port power switches to trigger global shutdown. IC Role / Device Role / Timing Role: Fault aggregation node; must respond within 100ns to prevent latch-up cascades. Use Value: 6.5ns max tPD at 5V ensures sub-100ns fault propagation, meeting USB 2.0 power sequencing requirements. |
| Laptop Embedded Controller Interface | Automotive Body Control Module |
|
Use Scenario: Merging lid-open and keyboard-press wake events to assert SLP_S3# in Intel chipset platforms. IC Role / Device Role / Timing Role: Wake-event combiner; operates at 3.3V with 5V-tolerant GPIO from EC. Use Value: Input tolerance avoids level-shifter components, simplifying BOM and layout for space-constrained EC interfaces. |
Use Scenario: Consolidating door-lock request signals from multiple door modules before feeding central BCM logic. IC Role / Device Role / Timing Role: Signal aggregator in 12V automotive systems using 3.3V domain MCU and 5V sensor interface ICs. Use Value: IOFF protection prevents backfeed from powered door modules into unpowered BCM during sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC32APWR | Wider industrial temp range (−40°C to +125°C vs. −40°C to +125°C), identical SO-14 pinout, but lacks IOFF and Schmitt inputs | Not suitable for partial power-down or noisy switch inputs; requires external hysteresis or level shifters | Select only if IOFF and Schmitt features are unused and cost is primary driver |
| 74AHC32D,118 | Higher speed (tPD ≤ 4.2ns typ at 5V), same SO-14 package, but input tolerance limited to VCC+0.5V (no 5.5V tolerance) | Cannot interface 5V signals into 3.3V systems without external clamping or translation | Prefer when maximum speed is critical and all logic domains share same VCC |
Compared with SN74LVC32APWR and 74AHC32D,118, the 74LV32AS14-13 uniquely combines 5.5V input tolerance, IOFF, and Schmitt inputs in a single SO-14 package-making it the only choice for mixed-voltage, hot-swap, or noisy-environment OR-gating where reliability trumps raw speed.

FAQ
Can 74LV32AS14-13 be used with 1.8V logic?
No. The absolute minimum VCC is 2.0V per datasheet Recommended Operating Conditions. At 1.8V, VIH thresholds fall below valid logic-high levels, and output drive collapses below specification-operation is not guaranteed and may result in metastability or excessive ICC.
Does the IOFF feature require external pull-ups or pull-downs?
No. IOFF places outputs in high-impedance state when VCC = 0V, regardless of input states. No external biasing is needed-inputs can float, be tied high/low, or driven externally without affecting output leakage or integrity.
What is the maximum capacitive load this device can drive reliably?
The datasheet specifies switching characteristics up to CL = 50pF. Driving >50pF increases propagation delay nonlinearly and may cause ringing or undershoot. For >50pF loads, add series termination or buffer stages-do not exceed 100pF without validation.
Is the SO-14 package lead-free and RoHS compliant?
Yes. Per Diodes Incorporated documentation, 74LV32AS14-13 is fully RoHS 2 compliant (2011/65/EU), lead-free, halogen-free, and antimony-free-verified via material declarations and JESD22 testing, with full traceability to manufacturing lot.
