SN74HCT240ANS is listed in the Buffers, Drivers, Receivers, Transceivers range at ChipApex. The manufacturer field lists Texas Instruments. Its product description is PROTOTYPE. Review the specifications below when checking this part for your BOM.
The SN74HCT240ANS is an octal buffer and line driver from the Texas Instruments 74HCT logic family. It features eight inverting outputs with three-state capability, controlled by two separate output-enable inputs. The device operates within a supply voltage range of 4.5V to 5.5V. It utilizes a 20-pin Small Outline (SOIC) package designed for surface-mount installation. The component supports operation across an extended temperature range from -40°C to +85°C.
Verify that the specific suffix 'ANS' corresponds to the 20-SOIC package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the required package style and temperature rating specifications.
Select this component when interfacing between CMOS logic and TTL-compatible devices requiring 5V operation. The HCT series ensures compatibility with standard TTL input thresholds while maintaining CMOS noise immunity. Verify that the 20-SOIC package dimensions fit the target PCB layout constraints and thermal requirements.
This part belongs to the widely adopted 74HCT logic family, which bridges the gap between older TTL standards and modern CMOS technology. The SN74HC240 series offers similar functionality but with wider voltage ranges, whereas the HCT variant is optimized specifically for 5V systems. This component serves as a fundamental building block for digital data routing and signal conditioning.
