DM74ALS133N

Inverter Gates Overview

The DM74ALS133N is a single 13-input NAND gate from the Advanced Low-power Schottky (ALS) logic family. It operates within a supply voltage range of 4.5V to 5.5V and supports a free air operating temperature of 0°C to +70°C. The device utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process. Key electrical characteristics include a HIGH level input voltage of 2V minimum, a LOW level output current capability of 8mA, and propagation delays with a maximum of 5ns for HIGH-to-LOW transitions at 50pF load.

Inverter Gates Feature Summary

• Performs logic NAND function using a single gate structure
• Functionally and pin-for-pin compatible with Schottky and low power Schottky TTL counterparts
• Switching specifications guaranteed over full temperature and VCC range

Inverter Gates Applications

• Digital logic circuits requiring multi-input NAND operations
• Memory systems utilizing ALS logic families
• Microprocessor interface designs

Inverter Gates Procurement Notes

Verify the specific package configuration, as the N suffix denotes a 16-lead Plastic Dual-In-Line Package (PDIP). Confirm that the application environment remains within the recommended operating temperature range of 0°C to +70°C. Ensure supply voltage stays between 4.5V and 5.5V to maintain specified electrical performance. Check for RoHS compliance status if required by project specifications.

Inverter Gates Selection Notes

Select this component when a high fan-in NAND gate is required in a design constrained by the ALS logic family standards. It serves as a direct replacement for older Schottky or Low Power Schottky devices where pin compatibility is critical. Consider the 13-input requirement carefully, as fewer inputs may allow for simpler alternatives, while higher speeds might necessitate different logic families.

Inverter Gates Part Context

This part belongs to the DM74ALS series, representing Fairchild Semiconductor's implementation of Advanced Low-power Schottky technology. The series is designed to offer improved AC performance compared to standard Schottky TTL while maintaining lower power consumption than its predecessors. The DM74ALS133 specifically addresses applications needing complex logic gating in a compact 16-lead format.

Inverter Gates Replacement Considerations

The datasheet indicates functional and pin-for-pin compatibility with Schottky and low power Schottky TTL counterparts. Designers should verify that substitute parts meet the same switching specifications at 50 pF loads and operate within the identical voltage and temperature ranges.
