Nexperia USA Inc. 74LVC1G27GW-Q100H

Overview

74LVC1G27GW-Q100 from Nexperia is an automotive-qualified single 3-input NOR gate logic IC in TSSOP6 (SOT363-2) package, operating from 1.65 V to 5.5 V supply, with ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It enables level translation between 3.3 V and 5 V domains in automotive body control modules.

For engineers reviewing the 74LVC1G27GW-Q100 datasheet, 74LVC1G27GW-Q100 pinout, 74LVC1G27GW-Q100 application, or 74LVC1G27GW-Q100 equivalent, this device supports mixed-voltage interface design, AEC-Q100 Grade 1 compliance verification, propagation delay validation at 1.65–5.5 V, and IOFF leakage characterization during system power sequencing.

Technical Context

This device implements a single 3-input NOR Boolean function with fully buffered CMOS outputs and Schmitt-trigger inputs-ensuring robust signal integrity against slow-rising or noisy digital signals across wide voltage and temperature ranges. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current during hot-insertion or partial power-down scenarios.

The logic gate supports JEDEC-compliant voltage interfaces (JESD8-7/8-5/8C/36), operates from −40 °C to +125 °C, and delivers propagation delays as low as 1.0 ns (typ.) at 4.5–5.5 V, with input thresholds scaling proportionally to VCC for reliable operation across 1.65–5.5 V supply rails.

FAQ

Is the 74LVC1G27GW-Q100 pin-compatible with non-automotive variants like 74LVC1G27GW?

Yes, it shares identical SOT363-2 (TSSOP6) pinout, electrical characteristics, and marking layout with industrial-grade 74LVC1G27GW. The '-Q100' suffix denotes AEC-Q100 qualification and extended temperature screening-but mechanical and functional compatibility is maintained.

Can this NOR gate drive a 50 pF load at 10 MHz while maintaining timing integrity?

Yes: at VCC = 3.3 V, CPD = 12 pF and tpd ≤ 5.4 ns (max), resulting in <0.7 ns timing margin degradation at 10 MHz with 50 pF load. Verified via Nexperia's test circuit Fig. 6 with RL = 500 Ω and CL = 50 pF per Table 10.

What happens to the output when VCC is ramped down to 0 V during system shutdown?

The IOFF circuit activates automatically, forcing Y into high-impedance state regardless of input states. Measured IOFF leakage is ≤±2 μA at VCC = 0 V and VI/VO = 5.5 V, preventing back-current into powered downstream logic.

Does the Schmitt-trigger input eliminate the need for external RC filtering on noisy sensor lines?

It significantly reduces but does not eliminate need for filtering: hysteresis ≥0.3 V at 3.3 V suppresses noise spikes <0.3 V, yet sustained EMI or fast transients exceeding that threshold still require board-level filtering per ISO 11452-4.
