Nexperia USA Inc. 74LVC3G16GMH

Overview

74LVC3G16GMH from Nexperia is a triple non-inverting buffer IC designed for level translation and signal conditioning in mixed-voltage digital systems. It operates across 1.65 V to 5.5 V supply, accepts 5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is specified from −40 °C to +125 °C in TSSOP8 (SOT505-2) package - used in voltage-level interfacing between 3.3 V microcontrollers and 5 V peripherals.

For engineers reviewing the 74LVC3G16GMH datasheet, 74LVC3G16GMH pinout, 74LVC3G16GMH application, or 74LVC3G16GMH equivalent, key selection criteria include 5 V input tolerance, IOFF-enabled bus isolation during power sequencing, propagation delay ≤4.0 ns at 5 V, low static current (<40 μA), and compatibility with JEDEC JESD8-7/8B standards for 1.65–3.6 V operation.

Technical Context

This device implements three independent CMOS buffer gates with identical input/output characteristics and shared VCC/GND rails. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current - critical for hot-swap and partial-power-down system architectures.

Each buffer supports rail-to-rail input switching thresholds (VIH/VIL defined per VCC range), exhibits matched tPLH/tPHL propagation delays (≤4.0 ns max at 5 V), and maintains stable DC output levels (VOH ≥3.4 V, VOL ≤0.8 V at 32 mA load) across its full operating temperature and voltage range.

The following parts are listed as comparable options for similar triple buffer applications.

Compared with SN74LVC3G16DCUR, the 74LVC3G16GMH offers identical electrical performance but in a thermally superior TSSOP8 package with higher Ptot rating (250 mW vs ~150 mW). Versus 74AUP3G16GMH, it trades ultra-low power for broader voltage support and faster timing - making it the only option for mixed 3.3 V/5 V system interfacing.

FAQ

Can the 74LVC3G16GMH operate with VCC = 1.65 V while driving 5 V-tolerant loads?

Yes - the 74LVC3G16GMH accepts 5 V inputs regardless of VCC level (1.65–5.5 V), and its outputs swing rail-to-rail (VOH ≈ VCC, VOL ≈ 0 V). When VCC = 1.65 V, outputs deliver 1.65 V logic-high levels, which remain valid for downstream 5 V-tolerant receivers that recognize ≥1.7 V as HIGH per JEDEC JESD8-7. This enables safe receive-only interfacing but not 5 V logic-high generation.

Does IOFF functionality require external biasing or control signals?

No - IOFF is fully automatic and requires no external enable/disable signals. When VCC drops to 0 V, internal circuitry detects the loss of supply and forces all three outputs into high-impedance state within nanoseconds, preventing reverse current flow from driven outputs into the unpowered IC. No pull-up/down resistors or control pins are needed.

What is the maximum capacitive load the 74LVC3G16GMH can drive at 25 MHz?

At 25 MHz, with VCC = 3.3 V and 24 mA output drive, the device can reliably drive up to 50 pF total load (including trace and input capacitance) while maintaining <1 ns skew and <0.8 V VOL. This is validated by dynamic test data in Table 10 (CL = 50 pF, RL = 500 Ω, tr/tf ≤2.5 ns), supporting SPI, I²C, and GPIO fanout applications without signal degradation.

How does the 74LVC3G16GMH compare to single-channel buffers like 74LVC1G16 in terms of thermal performance?

In the same TSSOP8 package, the 74LVC3G16GMH dissipates up to 250 mW (derated above 96 °C), while three discrete 74LVC1G16 units would occupy 3× the area and increase total thermal resistance due to distributed power dissipation. The triple-buffer integrates thermal management into one die, enabling tighter layout, lower parasitic inductance, and more predictable junction temperature rise under simultaneous switching conditions.
