Overview
The SN700455DR is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the logic gates and inverters category, featuring open-collector outputs. The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to 85°C. It is housed in a 14-SOIC surface-mount package with a width of 3.90mm. The component has a maximum static current of 2 µA and provides output currents of 5.2mA for both high and low states. Propagation delay is specified at 22ns under 6V supply with 50pF load.
Feature Summary
- Contains four independent 2-input NAND logic gates
- Features open-collector output configuration
- Includes Schmitt trigger inputs for noise immunity
Applications
- Digital signal processing circuits requiring NAND logic functions
- Microcontroller interface logic conditioning
- General-purpose digital logic applications
Procurement Notes
Verify the exact part number SN700455DR against official Texas Instruments documentation to confirm specifications. Ensure compatibility with system voltage levels and package requirements. Check for RoHS compliance status and moisture sensitivity level before integration. Confirm that the open-collector output type meets the design needs for pull-up resistor implementation.
Selection Notes
Select this component when a quad 2-input NAND gate with open-collector outputs is required. The Schmitt trigger input feature makes it suitable for noisy environments or slow-rising signals. Consider the 14-SOIC package size for PCB layout constraints. Verify that the 2V to 6V supply range aligns with the target application power rails.
Part Context
This component is part of the Texas Instruments logic IC portfolio, specifically designed for general-purpose digital applications. It falls under the category of gates and inverters. The SN700455 variant typically denotes specific packaging or revision details within the broader 74HC or similar logic families, though precise family classification requires datasheet confirmation. It serves as a fundamental building block for complex digital systems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Texas Instruments documentation or authorized distributors for verified equivalents.
