Nexperia USA Inc. 74HC2G16GVH

Overview

74HC2G16GVH from Nexperia is a dual non-inverting buffer gate in SC-74 (SOT457) package, operating across 2.0 V to 6.0 V supply, delivering matched propagation delays (8–25 ns at VCC = 4.5–6.0 V, CL = 50 pF), ±25 mA output drive, and rail-to-rail input compatibility - used for signal buffering and level translation in industrial control I/O expansion.

For engineers reviewing the 74HC2G16GVH datasheet, 74HC2G16GVH pinout, 74HC2G16GVH application, or 74HC2G16GVH equivalent, key selection criteria include supply voltage range (2.0–6.0 V), guaranteed operation up to +125 °C, CMOS input compatibility with TTL-level inputs (via 74HCT variant), and TSSOP/SC-74 footprint compatibility for space-constrained PCBs.

Technical Context

This device implements two independent CMOS buffer stages with symmetrical HIGH/LOW output drive capability and balanced tPLH/tPHL propagation delays. It supports unlimited input rise/fall times and operates without external timing constraints.

All inputs tolerate voltages from GND to VCC regardless of supply level, and outputs swing within 0.16 V of rails under 5.2 mA load (VCC = 6.0 V). The design complies with JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards and features HBM ESD protection exceeding 2000 V.

FAQ

What is the maximum recommended operating frequency for 74HC2G16GVH?

The device has no specified maximum clock frequency, as it is a combinational buffer-not a clocked device. Its usable edge rate is limited by propagation delay (8–25 ns) and load capacitance. With 50 pF load and 6.0 V supply, it reliably handles input transitions up to ~20 MHz (based on 2× tPD margin), provided PCB routing minimizes stubs and crosstalk.

Can 74HC2G16GVH drive a 100 pF capacitive load?

Yes, but with degraded timing: propagation delay increases to ~35 ns (VCC = 6.0 V) and transition time extends to ~30 ns. Output voltage swing remains within specification (VOH ≥ 5.68 V, VOL ≤ 0.26 V), but system-level timing margins must be re-verified using the CL-dependent tPD curves in Table 9 of the datasheet.

Is 74HC2G16GVH pin-compatible with 74HC2G16GW?

Yes-both share identical pin configuration (1A, GND, 2A, 2Y, VCC, 1Y) and functional behavior. The only difference is package: GV uses SC-74 (SOT457), GW uses TSSOP6 (SOT363-2). Footprint dimensions differ (1.7 mm vs. 1.25 mm body width), so PCB land patterns are not interchangeable without redesign.

Does 74HC2G16GVH support partial power-down operation?

No. The device lacks Ioff (power-off protection) or IOZ (3-state) functionality. If VCC = 0 V, inputs and outputs become undefined and may draw excessive current if driven externally. For hot-swap or partial-power systems, use a 3-state buffer like 74HC2G125 or add series resistors to limit fault current.
