NXP Semiconductors 74LVC1G27GS,132

Overview

74LVC1G27GS,132 from Nexperia is a single 3-input NOR gate logic IC in XSON6 (SOT1202) 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 compact portable interface circuits.

For engineers reviewing the 74LVC1G27GS,132 datasheet, 74LVC1G27GS,132 pinout, 74LVC1G27GS,132 application, or 74LVC1G27GS,132 equivalent, key selection criteria include its 6-terminal XSON6 footprint, 1.0 × 1.0 × 0.35 mm body size, -40 °C to +125 °C temperature rating, and guaranteed 3.6 ns max propagation delay at 5 V.

Technical Context

This device implements a single 3-input NOR Boolean function with fully buffered CMOS outputs and Schmitt-trigger inputs-enabling robust operation with slow-rising signals and mixed-voltage interfacing. Its IOFF circuit actively disables outputs during power-down to prevent backflow current.

It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across voltage ranges and meets HBM ESD >2000 V and CDM >1000 V per JS-001/JS-002. Static and dynamic parameters are fully characterized from -40 °C to +125 °C.

FAQ

Can 74LVC1G27GS,132 be used with a 5 V microcontroller driving its inputs while VCC = 3.3 V?

Yes. Inputs are 5 V tolerant up to 5.5 V regardless of VCC setting, enabling direct connection to 5 V MCU GPIOs without external level shifters. This is explicitly supported by the datasheet's "Inputs accept voltages up to 5 V" feature and JESD36 compliance at 4.5–5.5 V.

Does the IOFF function protect against back-current when only VCC is powered down but inputs remain at 5 V?

Yes. When VCC = 0 V, the IOFF circuit disables the output buffer and limits input/output leakage to ±2 μA maximum, preventing destructive back-current flow through the device - a key requirement for hot-swap and partial power-down architectures.

What is the minimum recommended load capacitance for achieving the specified 4.5 ns propagation delay?

The 4.5 ns max tpd at VCC = 5 V is measured with CL = 50 pF and RL = 500 Ω, per Table 10. Performance degrades with higher capacitance; for loads >50 pF, propagation delay increases linearly and must be verified per actual layout parasitics.

Is the SOT1202 (XSON6) package of 74LVC1G27GS,132 compatible with standard reflow profiles for lead-free soldering?

Yes. The XSON6 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), supporting standard lead-free reflow profiles with peak temperatures up to 260 °C. No pre-bake is required prior to assembly.
