Nexperia USA Inc. 74LVC2G16GWH

Overview

74LVC2G16GWH from Nexperia is a dual non-inverting buffer gate with Schmitt-trigger inputs, designed for level translation between 3.3 V and 5 V logic domains in mixed-voltage systems. It features IOFF partial power-down protection, ±24 mA output drive at 3.0 V, and operates across 1.65 V–5.5 V supply range. Used in I/O expansion, bus buffering, and voltage-level interfacing in industrial control and portable electronics.

For engineers reviewing the 74LVC2G16GWH datasheet, 74LVC2G16GWH pinout, 74LVC2G16GWH application, or 74LVC2G16GWH equivalent, key selection criteria include input overvoltage tolerance to 5.5 V, guaranteed operation from –40 °C to +125 °C, propagation delay as low as 1.9 ns (VCC = 4.5–5.5 V), and IOFF-enabled backflow current prevention during power sequencing.

Technical Context

This device implements two independent CMOS buffer channels with Schmitt-trigger inputs that accept slow-rising/falling signals and provide hysteresis for noise immunity. Each channel supports bidirectional voltage translation without external components due to overvoltage-tolerant inputs and rail-to-rail output swing.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking reverse current flow from powered downstream logic into the unpowered IC. Static and dynamic characteristics are fully specified across –40 °C to +125 °C, with JEDEC-compliant voltage standards covering 1.65 V–5.5 V operation.

FAQ

Does 74LVC2G16GWH support true bidirectional level shifting?

No. The 74LVC2G16GWH is a unidirectional dual buffer: signals flow only from A inputs to Y outputs. While its overvoltage-tolerant inputs allow 5 V signals to be safely received at 3.3 V VCC, it does not provide automatic direction sensing or reverse-path buffering. For bidirectional translation, a dedicated bus transceiver like 74LVC4245 must be used.

What is the minimum supply voltage for guaranteed operation at 125 °C?

The datasheet specifies full functionality down to 1.65 V across –40 °C to +125 °C. At 125 °C, the minimum recommended VCC remains 1.65 V, with VIH/VIL thresholds adjusted per JESD8-7 (1.65 V–1.95 V range). No derating is required for supply voltage at maximum temperature-only total power dissipation must be managed per package thermal limits.

Can the IOFF feature be disabled or bypassed?

No. IOFF is an intrinsic, always-active circuit tied directly to VCC. When VCC drops below ~0.2 V, the IOFF circuit automatically places outputs in high-impedance state. There is no enable/disable pin or register control-it is hardware-enforced and cannot be overridden by design or configuration.

Is the 74LVC2G16GWH pin-compatible with older 74LVC2G16 variants like GW or GM?

Yes. The 74LVC2G16GWH shares identical TSSOP6 (SOT363-2) pinout, marking location, and functional behavior with 74LVC2G16GW. Both use pin 1 index in lower-left corner, same terminal numbering (1A–GND–2A–2Y–VCC–1Y), and identical DC/AC specifications. The 'H' suffix denotes tape-and-reel packaging variant-not a functional revision.
