SN74ALS133DE4

Overview

The SN74ALS133DE4 is a 13-input positive-NAND gate from the Texas Instruments ALS logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of 0°C to 70°C. The device features Schottky-clamped inputs for high-speed performance, with propagation delays ranging from 3 ns to 25 ns depending on transition direction. It provides a low-level output current capability of up to 8 mA and a high-level output current of -0.4 mA.

Feature Summary

• Contains a single 13-input positive-NAND gate performing Boolean NAND functions in positive logic.
• Features Schottky clamping on all inputs to minimize switching noise and improve speed.
• Provides standard TTL-compatible input and output voltage levels.

Applications

• High-speed digital logic circuits requiring complex input gating.
• Microprocessor-based systems utilizing address decoding or control logic.
• Memory addressing schemes involving multiple selection lines.

Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific package variant required, as datasheet documentation lists the D (SOIC) package status as obsolete while other variants remain active. Confirm RoHS compliance and lead finish specifications against the latest Package Option Addendum before finalizing procurement orders.

Selection Notes

Select this component when a single gate with thirteen inputs is necessary for logic reduction. Ensure the design accommodates the 0°C to 70°C commercial temperature range. Verify that the circuit load does not exceed the specified output current limits of 8 mA low and -0.4 mA high under the intended supply voltage conditions.

Part Context

This part belongs to the SN74ALS133 series, which includes military-grade SN54ALS133 variants. The device is part of the Advanced Low-Power Schottky (ALS) family, designed to offer faster switching speeds than standard LS logic while maintaining lower power consumption. It serves as a specialized logic gate for applications requiring high fan-in capabilities.

Replacement Considerations

Public confirmed substitute part numbers include SN74ALS133DR and SN74ALS133NSR. Verify pinout compatibility and electrical characteristics match the original design requirements before substitution.
