74AHCT2G241DC,125

Buffers, Drivers, Receivers, Transceivers Overview

The 74AHCT2G241DC,125 is a dual buffer/line driver with 3-state outputs manufactured by Nexperia USA Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device provides two non-inverting buffers, each controlled by independent active LOW (1OE) and active HIGH (2OE) output enable inputs. Inputs are overvoltage tolerant up to 5.5 V, allowing use in mixed-voltage environments. It is housed in an 8-lead VSSOP plastic package (SOT765-1).

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-level compatibility is required alongside CMOS performance characteristics. The VSSOP package offers space efficiency for dense layouts. Ensure the design environment supports the specified 4.5 V to 5.5 V supply range and that ESD protection requirements align with the documented HBM and CDM ratings.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Nexperia 74AHCT series, which combines the low power dissipation of CMOS technology with the robust input thresholds of TTL logic. The '2G' designation indicates a dual-function device in a compact package format, designed to replace older octal or quad drivers in modern miniaturized electronics while maintaining standard logic functionality.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet revision history notes that type numbers 74AHCT2G241GD were removed from the product line. Designers should verify current availability and consider alternative packages such as TSSOP if XSON variants are discontinued.

Buffers, Drivers, Receivers, Transceivers FAQ

How do the output enable inputs function?

The device has two independent output enables: 1OE is active LOW, and 2OE is active HIGH. Asserting these signals places the associated outputs into a high-impedance OFF-state.

What is the maximum input voltage tolerance?

The inputs are overvoltage tolerant up to 5.5 V, regardless of the supply voltage applied to VCC.
