DM74AS30N

Inverter Gates Overview

The DM74AS30N is an 8-input NAND gate belonging to the AS (Advance Schottky) TTL logic series. It operates within a supply voltage range of 4.5V to 5.5V and features a single channel with eight inputs. The device utilizes a 14-pin plastic dual in-line package (PDIP-14). Its switching response is specified into a 500Ω load and 50pF capacitance, ensuring compatibility with standard transmission line interfaces.

Inverter Gates Feature Summary

• Advanced oxide-isolated, ion-implanted Schottky process for improved performance
• Functional and pin-compatible with 74LS and standard Schottky counterparts
• Low impedance output characteristics suitable for driving terminated transmission lines

Inverter Gates Applications

• Memory system buffering
• Microprocessor interface circuits
• Communication systems data routing

Inverter Gates Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor assets were acquired by onsemi. Confirm that the component matches the original Fairchild specifications rather than subsequent onsemi revisions. Ensure the part status aligns with project requirements, noting potential availability constraints for legacy AS-series components.

Inverter Gates Selection Notes

Select this component when high-speed switching is required alongside low power dissipation compared to standard Schottky logic. It serves as a direct replacement for 74LS30 or SN74S30 in designs requiring backward compatibility. Verify that the 8-input configuration meets the logical requirements without necessitating additional gating stages.

Inverter Gates Part Context

This device is part of the Advance Schottky (AS) family, designed to offer faster switching speeds than LS-TTL while consuming less power than standard S-TTL. The DM74AS30N specifically provides an 8-input NAND function, commonly used for complex decoding or enable signals in digital logic architectures.
