74HC126PW-Q100J

Overview

The Nexperia 74HC126PW-Q100J is a quad buffer and line driver featuring three-state outputs, qualified to AEC-Q100 Grade 1 standards for automotive use. It operates within a supply voltage range of 2.0 V to 6.0 V and functions across an ambient temperature range of -40 °C to +125 °C. The device utilizes a TSSOP14 package (SOT402-1) with four independent data enable inputs (nOE). When nOE is LOW, outputs enter a high-impedance OFF-state; when HIGH, they transmit input signals. Inputs include clamp diodes for overvoltage tolerance.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard
• Wide supply voltage operation from 2.0 V to 6.0 V
• High noise immunity and CMOS low power dissipation
• Latch-up performance exceeding 100 mA per JESD 78 Class II Level B

Applications

• Automotive electronic systems requiring signal buffering
• Mixed voltage environments utilizing overvoltage tolerant inputs
• Data bus isolation and line driving applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Confirm that the component meets the required AEC-Q100 Grade 1 qualification status for your target application. Ensure compatibility with your system's voltage levels and temperature ranges before finalizing procurement orders.

Selection Notes

Select this component when a quad non-inverting 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. Consider the TSSOP14 package constraints regarding thermal dissipation and board space requirements during the design phase.

Part Context

This part belongs to the Nexperia 74HC_HCT126_Q100 family of logic ICs. It is specifically the HC variant, which accepts CMOS input levels, distinct from the HCT variant that accepts TTL levels. The 'Q100' designation indicates automotive qualification, while 'PW' specifies the TSSOP14 plastic thin shrink small outline package.

Replacement Considerations

Direct substitutes include the 74HCT126PW-Q100J for TTL-compatible interfaces. For SO14 packages, consider the 74HC126D-Q100J. Verify pinout and electrical characteristics match before substitution.
