Nexperia USA Inc. 74LVC1G17GZYL

Overview

74LVC1G17GZYL from Nexperia is a single-channel Schmitt-trigger buffer IC designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V, accepts overvoltage-tolerant inputs up to 5.5 V, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and is qualified for -40 °C to +125 °C operation - enabling robust level translation between 3.3 V and 5 V logic domains in industrial control interfaces.

For engineers reviewing the 74LVC1G17GZYL datasheet, 74LVC1G17GZYL pinout, 74LVC1G17GZYL application, or 74LVC1G17GZYL equivalent, key selection criteria include hysteresis voltage (0.41–0.88 V), propagation delay (0.7–6.5 ns), input threshold symmetry (VT+ and VT−), IOFF leakage (<±2 μA at VCC = 0 V), and XSON5 package compatibility with side-wettable flanks for automated optical inspection.

Technical Context

The 74LVC1G17GZYL implements a CMOS-based Schmitt-trigger transfer function with asymmetric input thresholds (e.g., VT+ = 1.26–2.79 V, VT− = 0.25–2.27 V at VCC = 1.8–5.5 V) and fixed hysteresis (VH = 0.41–0.88 V). Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It supports unlimited input rise/fall times and direct TTL-level interfacing while maintaining noise immunity via hysteresis. The device complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full supply range and temperature grade.

FAQ

What is the purpose of the n.c. terminal in the SOT8065-1 package?

The n.c. (no-connect) terminal in the 74LVC1G17GZYL's SOT8065-1 package is an electrically isolated pad tied only to the die paddle. It serves no signal function but improves thermal dissipation and mechanical stability. It may be left unconnected or grounded to enhance heat transfer in thermally demanding applications.

Does the 74LVC1G17GZYL support true bidirectional level translation?

No - the 74LVC1G17GZYL is a unidirectional Schmitt-trigger buffer (input A → output Y). While its overvoltage-tolerant input allows connection to higher-voltage sources, the output swings only between GND and VCC. True bidirectional translation requires dedicated bus-switch or auto-direction-sensing devices.

How does the IOFF feature behave during power sequencing?

When VCC drops to 0 V, the IOFF circuit disables the output driver, presenting a high-impedance state at Y and limiting leakage current to <±2 μA. This prevents backflow from live downstream circuits into the unpowered IC - critical for safe hot-swap and staggered power-up sequences in modular systems.

Can the 74LVC1G17GZYL replace standard inverters like the 74LVC1G04 in debounce circuits?

Yes - unlike the 74LVC1G04 (standard inverter), the 74LVC1G17GZYL provides built-in hysteresis (VH ≥ 0.41 V), making it inherently suited for debouncing without external resistors or RC networks. Its Schmitt-trigger response eliminates metastability and chatter in mechanical switch inputs without additional components.
