74AHCT126PW,118

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT126PW,118 is a quad buffer and line driver featuring three-state outputs controlled by active HIGH output enable inputs (nOE). It operates within a supply voltage range of 4.5 V to 5.5 V. The device accepts TTL input levels and provides balanced propagation delays with Schmitt-trigger action on all inputs. Inputs are overvoltage tolerant, allowing operation in mixed voltage environments. It is specified for ambient temperatures from -40 °C to +125 °C and housed in a TSSOP14 package.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering code 74AHCT126PW,118 against the manufacturer's current product database to confirm availability and revision status. Ensure that the TSSOP14 package variant matches the design requirements. Cross-reference the datasheet revision date to confirm compliance with current JEDEC standards and RoHS directives before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance characteristics. The AHCT series is appropriate for interfacing between legacy TTL logic and modern CMOS circuits. Verify that the operating temperature range meets the environmental constraints of the target application and that the TSSOP14 package dimensions fit the available PCB space.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHCT126 family of quad buffers with three-state outputs. It shares functional similarities with the 74AHC126 but differs in input threshold specifications to support TTL logic levels. The PW suffix indicates the TSSOP14 plastic thin shrink small outline package, distinguishing it from other package options like SO14 or DHVQFN14 within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible substitutes include the 74AHCT126D,118 (SO14 package) and the 74AHCT126BQ (DHVQFN14 package). Other variants within the 74AHCT126 family may be considered if package form factor changes are acceptable.
