Product details

Overview

DM74ALS133N from Fairchild Semiconductor is a 13-input NAND gate IC in a 16-lead PDIP package, operating at VCC = 4.5–5.5 V with propagation delays as low as 3 ns (tPLH) and 5 ns (tPHL), rated for 0°C to +70°C industrial temperature range, and delivering 8 mA sink current (IOL) - used in high-density combinational logic control circuits.

For engineers reviewing the DM74ALS133N datasheet, pinout, applications, or equivalent options, key selection factors include guaranteed AC performance over full temperature/VCC range, Schottky TTL compatibility, input clamp voltage (VIK = −1.5 V), output drive capability (IO = −112 mA), and JEDEC MS-001 0.300" wide PDIP mechanical fit.

Technical Context

The DM74ALS133N implements a single 13-input NAND function using advanced oxide-isolated, ion-implanted Schottky TTL process technology. It guarantees switching specifications at CL = 50 pF and supports rail-to-rail logic-level interpretation with VIH = 2.0 V min and VIL = 0.8 V max.

Its output stage delivers robust drive strength: VOL = 0.4 V max at IOL = 4 mA and IO = −112 mA peak sink capability under VCC = 5.5 V. Input leakage is tightly controlled: IIH = 20 µA max at VIH = 2.7 V and IIL = −0.1 mA at VIL = 0.4 V.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	4.5 V to 5.5 V - ensures stable operation across standard TTL supply tolerance.
tPLH / tPHL	3 ns / 5 ns min - enables high-speed logic decision paths in dense control planes.
IOL / IOH	8 mA / −0.4 mA - drives multiple TTL inputs without external buffering.
VIH / VIL	2.0 V / 0.8 V - compatible with standard TTL and LS logic thresholds.
Operating Temp	0°C to +70°C - qualified for commercial/industrial ambient environments.
Input Clamp Voltage	VIK = −1.5 V - protects against negative transients during hot insertion or ESD events.
θJA (PDIP)	85.0°C/W - defines thermal resistance for board-level power dissipation planning.

Pinout & Package

DM74ALS133N is housed in a 16-lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300" wide, with 0.100" lead pitch and through-hole mounting.

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.

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	Identical pinout, same AC/DC specs; manufactured by Texas Instruments post-Fairchild acquisition.	No functional or layout change required; identical JEDEC MS-001 PDIP footprint.	Select when sourcing from TI-distributed channels or requiring TI-specific documentation.
DM74LS133N	Slower propagation (tPHL up to 35 ns), lower IOL (4 mA), higher ICC (1.6 mA typical).	Acceptable where speed < 10 MHz and fanout ≤ 4; not suitable for high-speed bus arbitration.	Choose for cost-sensitive legacy designs where timing margins allow 3× slower response.

Compared with SN74ALS133N, DM74ALS133N offers identical functionality and form factor but reflects original Fairchild branding and traceability; versus DM74LS133N, it provides 3× faster switching and double the output drive, enabling denser logic integration without added buffers.

FAQ

What logic function does the DM74ALS133N perform?

The DM74ALS133N performs a single 13-input NAND logic function: its output Y is LOW only when all 13 inputs (A through M) are HIGH; otherwise, Y is HIGH. This behavior is defined in the device's function table and verified across the full 0°C to +70°C operating range and 4.5–5.5 V supply voltage window. The DM74ALS133N implements this function using oxide-isolated, ion-implanted Schottky TTL technology.

Is the DM74ALS133N pin-compatible with other 13-input NAND gates?

Yes, the DM74ALS133N is pin-for-pin compatible with the 74S133 and 74LS133 in the same 16-lead PDIP package (JEDEC MS-001). Its pinout matches industry-standard 13-input NAND layouts: inputs A–M occupy pins 1–13, VCC is pin 16, GND is pin 14, and output Y is pin 15. This compatibility allows direct substitution in legacy designs without PCB modification - confirmed in Fairchild's DS006201 datasheet.

What are the absolute maximum ratings for the DM74ALS133N?

The DM74ALS133N 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 limits may compromise reliability or cause permanent damage. These values are specified in the "Absolute Maximum Ratings" section of the official Fairchild DS006201 datasheet and are distinct from recommended operating conditions.

Does the DM74ALS133N require external pull-up resistors on its inputs or output?

No, the DM74ALS133N does not require external pull-up resistors. Its inputs are TTL-compatible with defined VIH (2.0 V min) and VIL (0.8 V max) thresholds and exhibit low input current (IIH ≤ 20 µA, IIL ≥ −0.1 mA). The output is actively driven both HIGH and LOW, with IOH = −0.4 mA and IOL = 8 mA capability - sufficient to interface directly with standard TTL loads without pull-ups. This behavior is confirmed in the Electrical Characteristics table of the DM74ALS133N datasheet.

How does the DM74ALS133N differ from the DM74LS133N in practical use?

The DM74ALS133N delivers significantly faster switching (tPHL min = 5 ns vs. 35 ns for DM74LS133N), higher output drive (IOL = 8 mA vs. 4 mA), and lower supply current (ICC = 0.8 mA max vs. 1.6 mA). In practice, this means the DM74ALS133N supports higher clock rates in bus control logic and can drive more downstream inputs without buffering - verified under identical 50 pF load and 4.5–5.5 V supply conditions per DS006201.
