Product details

Overview

DM74ALS133M from Fairchild Semiconductor is a 13-input NAND gate IC in a 16-lead SOIC package, operating at VCC = 4.5–5.5 V, with propagation delays as low as 3 ns (tPLH) and output drive capability of −112 mA (IO), used in high-density TTL logic systems requiring wide-input combinational logic.

For engineers reviewing the DM74ALS133M datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed AC performance across 0°C to +70°C, compatibility with Schottky and LS-TTL families, and verified 50 pF load switching behavior.

Technical Context

This device implements a single 13-input NAND function (Y = A·B·C·D·E·F·G·H·I·J·K·L·M) using advanced oxide-isolated, ion-implanted Schottky TTL process technology. It delivers deterministic logic inversion with rail-to-rail input voltage thresholds (VIL = 0.8 V, VIH = 2.0 V) and supports standard TTL interfacing.

Designed for full-temperature-range operation (0°C to +70°C), it guarantees switching characteristics under RL = 500 Ω and CL = 50 pF conditions, with tPHL up to 25 ns and tPLH as low as 3 ns - outperforming standard Schottky and low-power Schottky TTL counterparts in speed.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL supply rails and margin against ripple or droop.
Input Count	13 inputs (A–M) - enables single-gate implementation of complex enable/disable or fault-aggregation logic without cascading.
tPLH / tPHL	3 ns / 5 ns (min) - supports high-speed synchronous control paths in bus arbitration or memory address decoding.
IOL / IOH	8 mA / −0.4 mA - drives standard TTL loads directly; sufficient fanout for legacy backplane or board-level logic networks.
VIH / VIL	2.0 V / 0.8 V - matches standard TTL input thresholds, enabling seamless interoperation with 74LS/74S/74ALS families.
Operating Temp	0°C to +70°C - qualified for commercial-grade industrial control, instrumentation, and computing applications.

Pinout & Package

DM74ALS133M is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body (Package Number M16A), with thermal resistance θJA = 111.0°C/W.

Pin/Terminal	Circuit Role	Design Meaning
1–13 (A–M)	NAND Inputs	13 independent TTL-compatible logic inputs; all must be HIGH for LOW output; any LOW forces HIGH output.
14	GND	Ground reference for all internal circuitry and output stage; requires low-impedance PCB connection.
15	Y	Active-low NAND output; sinks up to 8 mA or sources −0.4 mA; electrically compatible with standard TTL loads.
16	VCC	Positive supply terminal; must be decoupled locally with 0.1 µF ceramic capacitor near pin.

Key Features

Feature	Design Value
13-input single-gate NAND	Reduces board space and interconnect complexity versus multi-stage NAND implementations in enable logic or watchdog circuits.
Guaranteed 50 pF switching	Ensures predictable timing in real-world PCB traces and capacitive loads without derating or external buffering.
Full temperature range AC specs	Eliminates need for worst-case timing analysis across 0°C to +70°C - simplifies design validation for industrial environments.
Pin-for-pin compatible with 74S133/74LS133	Enables drop-in replacement in existing designs using Schottky or low-power Schottky 13-input NANDs.

Applications

Bus Arbitration Logic	Memory Address Decoding
Use Scenario: Resolving contention among multiple masters on a shared data bus by aggregating grant signals. IC Role / Device Role / Timing Role: 13-input NAND acts as wired-OR negative-enable aggregator; output asserts bus grant only when all 13 request lines are active. Use Value: Single-gate solution avoids propagation delay stacking and reduces routing congestion in dense backplane layouts.	Use Scenario: Generating chip-select signals for peripheral devices in microprocessor-based systems with large address spaces. IC Role / Device Role / Timing Role: DM74ALS133M evaluates up to 13 address or attribute bits to assert a low-active select line synchronously with address valid. Use Value: Meets tight tPHL ≤ 25 ns requirement for 8–10 MHz CPU buses without adding pipeline stages.
Fault Detection Aggregation	Power-On Reset Sequencing
Use Scenario: Monitoring 13 independent subsystem health signals (e.g., voltage rails, thermal sensors, watchdog timeouts) in telecom line cards. IC Role / Device Role / Timing Role: DM74ALS133M outputs HIGH if any monitored signal fails (LOW), triggering centralized fault interrupt. Use Value: Eliminates need for discrete diode-OR networks or FPGA resources, improving MTBF and reducing BOM count.	Use Scenario: Enabling power sequencing controllers only after 13 critical supplies reach regulation. IC Role / Device Role / Timing Role: Acts as final "all-rails-good" combinatorial gate whose output releases reset to downstream logic. Use Value: Guarantees deterministic startup order with no race conditions, leveraging fixed 3 ns tPLH for precise timing alignment.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 13-input NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ALS133N	Dual-in-line (PDIP) package; θJA = 85.0°C/W; otherwise identical logic, timing, and DC specs.	Better thermal performance in low-airflow environments; not suitable for surface-mount assembly.	Select SN74ALS133N for through-hole prototyping or legacy repair where SOIC rework is impractical.
74F133PC	Fast TTL family; faster tPHL (3.5 ns typ), higher ICC (12 mA), wider VCC range (4.5–5.5 V), but higher IIL (−1.6 mA).	Higher speed at cost of increased power and noise sensitivity; less tolerant of marginal input drive.	Choose 74F133PC only when sub-4 ns propagation is mandatory and power budget allows >10× ICC increase.

Compared with SN74ALS133N and 74F133PC, DM74ALS133M offers optimal balance of surface-mount compatibility, thermal resistance suited for compact PCBs, and proven reliability in commercial-temperature industrial logic systems - without compromising TTL interoperability or timing predictability.

FAQ

What logic function does the DM74ALS133M implement?

The DM74ALS133M implements a single 13-input NAND gate, where the output Y is LOW only when all 13 inputs (A through M) are HIGH; otherwise, the output is HIGH. This function is defined by the Boolean expression Y = A·B·C·D·E·F·G·H·I·J·K·L·M, and is electrically and functionally consistent across all operating conditions specified in the datasheet.

Is the DM74ALS133M pin-compatible with other 13-input NAND devices?

Yes, the DM74ALS133M is functionally and pin-for-pin compatible with the 74S133 and 74LS133, sharing identical pin assignments for inputs A–M, output Y, VCC, and GND. This compatibility enables direct substitution in legacy designs without PCB modification, provided the SOIC footprint is supported.

What are the absolute maximum ratings for the DM74ALS133M?

The DM74ALS133M has an absolute maximum supply voltage of 7 V, input voltage limit of 7 V, operating free-air temperature range of 0°C to +70°C, and storage temperature range of −65°C to +150°C. Exceeding these values may cause permanent damage, and the device is not tested or guaranteed at these limits.

Does the DM74ALS133M support operation at 3.3 V?

No, the DM74ALS133M is specified only for VCC = 4.5 V to 5.5 V and is not characterized or guaranteed for 3.3 V operation. Its input thresholds (VIH = 2.0 V, VIL = 0.8 V) and output drive levels are optimized for 5 V TTL systems; use at 3.3 V may result in undefined logic states or degraded noise margins.

How is thermal performance characterized for the DM74ALS133M package?

The DM74ALS133M uses a 16-lead SOIC package (M16A) with a typical junction-to-ambient thermal resistance (θJA) of 111.0°C/W. This value assumes standard JEDEC test conditions (single-layer copper, 1 in² pad); actual thermal performance depends on PCB layout, copper area, and airflow, and must be validated in the target system.
