Inverter Gates datasheet and documents for SN74LS03MEL

SN74LS03MEL

Inverter Gates Overview

The SN74LS03MEL is a Low Power Schottky (LS) quad two-input NAND gate with open-collector outputs. It operates within a supply voltage range of 4.75 V to 5.25 V. The device features a typical propagation delay of 15 ns and a maximum power dissipation of 100 mW per package. It supports a high-level output current of -400 µA and a low-level sink current of up to 8 mA. The component is rated for an operating temperature range from -55°C to +125°C.

Inverter Gates Feature Summary

Open-collector output configuration enables wired-AND logic connections and flexible voltage level shifting capabilities.

Inverter Gates Applications

Bus line drivers requiring wired-AND functionality
Logic interface circuits for voltage translation
General-purpose digital logic processing

Inverter Gates Procurement Notes

Verify the MEL suffix indicates a specific military or space-grade qualification standard distinct from commercial variants. Confirm the manufacturer source, as ON Semiconductor typically uses different suffixes for this part number. Ensure the datasheet explicitly defines the environmental testing requirements associated with the MEL designation before procurement.

Inverter Gates Selection Notes

Select this component when open-collector NAND logic is required in harsh environments due to its extended temperature range. Verify that the system can accommodate the slower switching speeds inherent to the LS series compared to faster alternatives like ALS or F families. Ensure pull-up resistors are correctly sized for the desired load capacitance and voltage levels.

Inverter Gates Part Context

This component belongs to the Texas Instruments SN54/74LS family of Low Power Schottky TTL logic devices. The SN54 variant covers the full military temperature range, while the SN74 covers the commercial range. The SN74LS03 specifically provides four independent two-input NAND gates with open-collector outputs, distinguishing it from the standard push-pull output SN74LS00.
