74AHCT126T14-13

Overview

The Diodes Incorporated 74AHCT126T14-13 is a quadruple 3-state buffer gate housed in a TSSOP-14 surface-mount package. Designed for operation within a 4.5V to 5.5V supply voltage range, the device features four independent non-inverting buffers with separate active-high data enable pins. It provides output drive capabilities of 8mA at VCC = 4.5V and incorporates Schmitt trigger action at all inputs. The component operates across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides four independent buffer gates with separate active-high data enable pins for precise output control
• Incorporates Schmitt trigger action at all inputs to ensure signal integrity
• Features TTL voltage level compatible inputs for broad interface compatibility
• Includes robust ESD protection exceeding JESD standards for machine, human body, and charged device models

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• Televisions, DVDs, DVRs, and set-top boxes

Procurement Notes

Verify the specific TSSOP-14 package designation (suffix T14) matches the required footprint during procurement. Confirm RoHS compliance and lead-free status requirements against project specifications. Ensure the operating environment remains within the specified -40°C to +125°C temperature range. Validate that the 4.5V to 5.5V supply voltage constraints align with the system power architecture before finalizing orders.

Selection Notes

Select this component when a quadruple buffer with individual high-active enables is required for 5V logic systems. The AHCT series ensures TTL input compatibility while maintaining CMOS low power consumption characteristics. Consider the TSSOP-14 package for applications requiring compact surface-mount solutions. Verify that the 8mA output drive capability meets the load requirements of the connected circuitry.

Part Context

This part belongs to the 74AHCT126 family of quadruple 3-state buffers manufactured by Diodes Incorporated. It shares functional similarities with other members of the 74AHC and 74HCT logic families but is specifically optimized for 5V operation with TTL-compatible inputs. The T14 suffix denotes the TSSOP-14 package variant, distinguishing it from the SO-14 package version.

Replacement Considerations

The 74AHCT126S14-13 serves as a direct pin-compatible alternative utilizing the SO-14 package instead of TSSOP-14.
