Overview
The SN74F38NSR is a logic gate device from Texas Instruments 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 an operating free-air temperature range of 0°C to 70°C. The component utilizes a 14-pin SOP (NS) package for surface-mount installation.
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 functions when connected to other open-collector outputs
Applications
- Implementing active-low wired-OR logic functions
- Implementing active-high wired-AND logic functions
- Generating higher output high-level voltage levels
Procurement Notes
Verify the specific ordering suffix 'SR' corresponds to the SOP (NS) package type and 2000-unit large tape-and-reel carrier configuration. Confirm RoHS compliance status and lead finish details via the manufacturer's current packaging data sheet, as these attributes are subject to change without notice.
Selection Notes
Select this component when a quad 2-input NAND function with open-collector outputs is required in a surface-mount format. Ensure the design includes appropriate external pullup resistors for the open-collector outputs. Verify that the 0°C to 70°C commercial temperature range meets the application requirements.
Part Context
This part belongs to the SN74F38 series of logic gates manufactured by Texas Instruments. The series provides standard TTL-compatible logic functions in various package options including plastic small-outline packages and ceramic chip carriers. The SN74F38 variant specifically targets commercial temperature ranges.
