DM74AS1000AN

Inverter Gates Overview

The DM74AS1000AN is a quadruple 2-input NAND driver manufactured by onsemi (formerly Fairchild Semiconductor). It utilizes an advanced oxide-isolated, ion-implanted Schottky TTL process. The device operates within a supply voltage range of 4.5V to 5.5V and supports a free air operating temperature from 0°C to +70°C. Key electrical parameters include a propagation delay of 14ns at 50pF load, high-level output current of -48mA, and low-level output current of 48mA. It is housed in a 14-Lead Plastic Dual-In-Line Package (PDIP) with a width of 0.300 inches.

Inverter Gates Procurement Notes

Verify the manufacturer origin, as this component was originally produced by Fairchild Semiconductor before its semiconductor business acquisition. Confirm the package type matches the specific 'N' suffix designation for the PDIP variant. Ensure compliance with RoHS directives if required for the target application environment. Check for obsolescence status or lifecycle notices from the current supplier.

Inverter Gates Selection Notes

Select this component when high-speed switching performance is required alongside robust output drive capabilities. The AS series offers superior speed compared to standard LS logic while maintaining lower power consumption than older Schottky variants. Consider the PDIP package for through-hole mounting requirements. Verify that the 14ns propagation delay meets the timing constraints of the system design.

Inverter Gates Part Context

This part belongs to the 74AS (Advanced Schottky) logic family, designed for high-speed digital applications. It serves as a driver version of the standard NAND gate, providing enhanced output current. The DM74AS1000A is functionally compatible with other devices in the 74AS series, facilitating system upgrades where speed is critical.

Inverter Gates FAQ

What is the maximum low-level output current?

The maximum low-level output current (IOL) is 48 mA.

Does the device support bidirectional data transmission?

No, the DM74AS1000AN is a unidirectional driver performing the NAND function, not a bus transceiver.
