Nexperia USA Inc. 74AUP3G16DCH

Overview

74AUP3G16DCH from Nexperia is a low-power triple buffer IC with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering ICC ≤ 0.9 μA max static current, tpd ≤ 4.2 ns at 3.0 V/CL = 10 pF, and IOFF-enabled partial power-down protection. It serves as a noise-immune signal conditioner in battery-powered sensor interfaces and voltage-level translation paths between mixed-supply logic domains.

For engineers reviewing the 74AUP3G16DCH datasheet, 74AUP3G16DCH pinout, 74AUP3G16DCH application, or 74AUP3G16DCH equivalent, key selection criteria include its ultra-low ICC across full VCC range, guaranteed IOFF behavior at VCC = 0 V, Schmitt-trigger hysteresis for slow-edge tolerance, and VSSOP8 package compatibility with high-density PCB layouts.

Technical Context

This device implements three independent non-inverting buffers, each with Schmitt-trigger input thresholds (VIH/VIL varying with VCC) to reject noise on slow-rising/falling signals. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±0.75 μA at 3.6 V I/O stress.

Dynamic performance is load- and voltage-dependent: propagation delay ranges from 1.4 ns (VCC = 3.6 V, CL = 5 pF) to 32.1 ns (VCC = 0.8 V, CL = 30 pF), while CPD remains stable at 2.5–4.0 pF across VCC, enabling accurate dynamic power estimation via PD = CPD × VCC² × fi × N.

FAQ

Does 74AUP3G16DCH support true bidirectional signal flow?

No. The 74AUP3G16DCH is a unidirectional non-inverting buffer with fixed input (pins 1/3/6) and output (pins 2/5/7) assignments. It lacks internal direction-control logic or bus-switch architecture. For bidirectional applications, consider dedicated bus transceivers like the 74AUP2G240 or discrete MOSFET-based solutions.

Can the Schmitt-trigger inputs be disabled to use standard CMOS thresholds?

No. Schmitt-trigger action is inherent to the input stage design and cannot be disabled or bypassed. The hysteresis is fixed per VCC (e.g., ~0.3 V at 1.8 V, ~0.6 V at 3.3 V) and is not user-configurable. If standard CMOS thresholds are required, select non-Schmitt variants such as the 74AUP3G17.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies timing performance up to CL = 30 pF across all VCC conditions. Driving loads beyond 30 pF may increase propagation delay nonlinearly and risk overshoot/undershoot exceeding 10% of VCC. For >30 pF loads, add series termination or verify signal integrity with IBIS simulation using the official Nexperia model.

Is the 74AUP3G16DCH pin-compatible with older 74AUP3G16 variants in VSSOP8?

Yes. All 74AUP3G16 devices in SOT765-1 (VSSOP8) package share identical pinout, marking location (pin 1 indicator below marking code "5A"), and thermal/mechanical dimensions. The "DCH" suffix denotes tape-and-reel packaging per EIA-481-D standard, not a functional or pinout revision.
