74HC126D-Q100J

Overview

The Nexperia 74HC126D-Q100J 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 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device complies with JEDEC standards JESD8C and JESD7A, accepts CMOS input levels, and includes input clamp diodes for overvoltage tolerance. It is qualified to AEC-Q100 Grade 1 standards for automotive applications.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standards
• Three-state outputs controlled by active-high nOE inputs
• Input clamp diodes enabling interface to voltages exceeding VCC
• High noise immunity and latch-up performance exceeding 100 mA

Applications

• Automotive electronic systems requiring high reliability
• Mixed-voltage signal translation environments
• Bus-oriented memory and data transmission circuits

Procurement Notes

Verify the specific suffix 'J' against official Nexperia documentation to confirm reel packaging specifications. Confirm that the SO14 package variant matches the required SOT108-1 outline dimensions. Ensure design compliance with the specified AEC-Q100 Grade 1 qualification requirements before finalizing procurement orders.

Selection Notes

Select this component when a quad buffer with three-state control is required for automotive or industrial environments. It is suitable for translating signals between different voltage domains due to its overvoltage tolerant inputs. Verify that the CMOS input logic levels align with the source circuitry requirements.

Part Context

This part belongs to the Nexperia 74HC126-Q100 family of quad buffers and line drivers. It shares functional characteristics with the 74HCT126-Q100 but differs in input logic level compatibility, supporting CMOS rather than TTL levels. The D package designation indicates the SO14 surface-mount configuration.

Replacement Considerations

The 74HCT126D-Q100J serves as a compatible alternative if TTL input levels are acceptable. Other variants within the 74HC126-Q100 family may be considered based on package preference, such as TSSOP14.
