74AHCT126PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHCT126PW,112 is a quad buffer and line driver featuring three-state outputs controlled by output enable inputs. 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 use as translators in mixed-voltage environments. It includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +85 °C and up to +125 °C.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Quad buffer/line driver with three-state outputs controlled by active-low output enable inputs
• TTL input level compatibility with overvoltage tolerant inputs for mixed-voltage translation
• Schmitt-trigger action on all inputs for improved noise immunity and tolerance to slow rise/fall times

Buffers, Drivers, Receivers, Transceivers Applications

• Bus interface applications requiring signal buffering
• Mixed-voltage environment signal translation between CMOS and TTL logic families
• Line driving for high-speed data transmission paths

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify current production status before design finalization, as availability may vary. Confirm package marking and pinout alignment with existing schematics. Ensure thermal management meets specifications for the intended ambient temperature range. Validate that input voltage levels remain within the overvoltage tolerance limits during all operating conditions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside three-state bus isolation capabilities. The AHCT series ensures direct interface with TTL logic levels while maintaining CMOS performance characteristics. Consider the TSSOP-14 package for surface-mount assembly requirements. Verify that the four-channel configuration matches the system's parallel data width needs.
