Product details

Overview

74AHCT32PW,112 from Nexperia is a quad 2-input OR gate IC in TSSOP-14 package, operating at 4.5–5.5 V supply, with 8 ns typical propagation delay, ±8 mA output drive, and TTL-compatible inputs. It performs basic Boolean OR logic in digital control signal routing for industrial PLC I/O modules.

For engineers reviewing the 74AHCT32PW,112 datasheet, 74AHCT32PW,112 pinout, 74AHCT32PW,112 application, or 74AHCT32PW,112 equivalent, key selection criteria include propagation delay matching, input threshold compatibility with legacy TTL systems, output current capability under capacitive load, and thermal performance in dense PCB layouts.

Technical Context

This device implements four independent 2-input OR gates using advanced silicon-gate CMOS technology. Each gate features buffered outputs, symmetrical propagation delays (t_PHL ≈ t_PLH), and guaranteed high/low output voltage levels across temperature and supply variation.

Input thresholds are fixed at 2.0 V (V_IH) and 0.8 V (V_IL) to ensure interoperability with standard TTL logic families. The design supports direct replacement of 74LS32 in mixed-logic systems without level-shifting circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Family	74AHCT - TTL-compatible CMOS with 5 V operation and LS-level input thresholds
Propagation Delay	8 ns max at V_CC = 5 V, C_L = 50 pF - ensures timing predictability in 25 MHz synchronous control paths
Output Drive	±8 mA at V_CC = 5 V - sufficient to drive 10 LS-TTL loads or 20 pF trace capacitance
Supply Voltage	4.5–5.5 V - compatible with regulated 5 V rails and tolerant of ±10% line variation
Operating Temp	−40°C to +125°C - qualified for extended industrial environments including motor drive control cabinets
ESD Rating	HBM 2000 V - meets IEC 61000-4-2 Level 2 for handling in non-ESD-protected assembly areas

Pinout & Package

Package: TSSOP-14 (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced for surface-mount reflow assembly on FR-4 PCBs with standard IPC-7351B footprint.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 8, 9, 12, 13	Input A/B per gate	Dedicated logic inputs for each of four OR gates; TTL-compatible thresholds enable direct connection to 74LS/74F outputs
3, 4, 10, 11	Output Y per gate	Push-pull CMOS outputs capable of sourcing/sinking 8 mA while maintaining VOH ≥ 4.4 V / VOL ≤ 0.5 V
7	GND	Ground reference for all internal logic and output stages; requires low-inductance connection to PCB ground plane
14	V_CC	Positive supply terminal; must be decoupled with 100 nF ceramic capacitor within 5 mm of pin

Key Features

Feature	Design Value
TTL-compatible input thresholds	Ensures seamless integration into legacy 5 V TTL systems without external level shifters or resistor networks
Low dynamic power consumption	Typical ICC = 2 µA at 5 V and static conditions - reduces heat buildup in high-density logic arrays
Overvoltage-tolerant inputs	Inputs withstand up to 5.5 V regardless of V_CC state - prevents latch-up during hot-insertion or power sequencing
Specified operation down to −40°C	Validated functionality in cold-storage automation and outdoor industrial enclosures without derating

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AHCT32PWRE4	Same logic function and pinout; RoHS-compliant variant with green molding compound and Pb-free terminations	No functional difference; preferred for new designs targeting IPC-J-STD-020 moisture sensitivity level 3 compliance	Select when lead-free assembly and JEDEC MSL-3 handling are required
74VHC32PW,118	Higher V_CC range (2–5.5 V); CMOS input thresholds (V_IH = 3.5 V) incompatible with TTL outputs	Requires level-shifting when interfacing with 74LS/74F devices; unsuitable for direct drop-in replacement	Choose only if system uses pure CMOS signaling and wide-supply flexibility is critical

Compared with SN74AHCT32PWRE4, the 74AHCT32PW,112 offers identical electrical behavior but lacks the green compound specification; versus 74VHC32PW,118, it provides guaranteed TTL interoperability at the cost of narrower supply range - making it the sole choice for mixed-logic industrial retrofits.

FAQ

What is the maximum clock frequency supported by the 74AHCT32PW,112?

The 74AHCT32PW,112 is not a clocked device and has no defined clock frequency. Its usable toggle rate is limited by propagation delay and load capacitance; with 50 pF load, maximum reliable switching frequency is approximately 62.5 MHz (1/(2 × 8 ns)). This applies only to repetitive square-wave input conditions, not guaranteed for data integrity in synchronous systems.

Can the 74AHCT32PW,112 drive an LED directly?

No. While its output can sink/source up to 8 mA, driving an LED requires current limiting and polarity alignment. With V_CC = 5 V and typical red LED V_F = 1.8 V, a 390 Ω series resistor is needed to limit current to ~8 mA. Direct connection without resistor risks exceeding absolute maximum ratings and degrading long-term reliability.

Is the 74AHCT32PW,112 suitable for 3.3 V operation?

No. The 74AHCT32PW,112 is specified only for 4.5–5.5 V operation. At 3.3 V, input thresholds become undefined, propagation delay increases unpredictably (>25 ns), and output drive falls below 1 mA - violating TTL compatibility and risking logic misinterpretation in mixed-voltage systems.

Does the 74AHCT32PW,112 include Schmitt-trigger inputs?

No. The 74AHCT32PW,112 uses standard CMOS input buffers with fixed TTL-compatible thresholds (V_IL = 0.8 V, V_IH = 2.0 V). It lacks hysteresis; for noisy signal environments, external RC filtering or dedicated Schmitt-trigger gates like 74AHCT14 must be used upstream.
