SN74F38N

Overview

The SN74F38N is a dual-supply voltage logic integrated circuit containing four independent 2-input NAND buffer gates with open-collector outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a low-level output current up to 64 mA. The device features propagation delays ranging from 1 ns to 13 ns depending on the transition direction. Designed for commercial applications, it functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Contains four independent 2-input NAND buffer gates
• Features open-collector outputs requiring external pullup resistors
• Supports active-low wired-OR or active-high wired-AND configurations

Applications

• Implementing active-low wired-OR logic functions
• Generating higher high-level output voltage levels
• Active-high wired-AND logic implementations

Procurement Notes

Verify the specific package type and manufacturer lot traceability upon receipt. Confirm that the component matches the SN74F38N designation and PDIP-14 form factor. Ensure the device meets the specified commercial temperature range requirements for your application environment before integration.

Selection Notes

Select this component when open-collector NAND functionality is required for wired-logic bus architectures. Consider the 64 mA low-level sink capability for driving moderate loads directly. Verify that the system design includes appropriate pullup resistors to ensure correct high-state output voltages.

Part Context

This part belongs to the Texas Instruments SN74F series of fast TTL logic devices. It provides standard 14-pin DIP packaging suitable for through-hole mounting. The device implements basic Boolean logic operations using open-collector technology, distinguishing it from standard push-pull output logic families.
