Diodes Incorporated 74LVC1G58DW-7

Overview

74LVC1G58DW-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in SOT363 package, supporting AND, OR, NAND, NOR, XOR, inverter, and non-inverting buffer configurations via input pin states. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, features 5.5V-tolerant inputs, and supports partial power-down via IOFF. It is used for voltage level shifting and signal isolation in portable electronics and mixed-voltage I/O interfaces.

For engineers reviewing the 74LVC1G58DW-7 datasheet, 74LVC1G58DW-7 pinout, 74LVC1G58DW-7 application, or 74LVC1G58DW-7 equivalent, this page provides verified functional configuration details, real-world timing behavior (tpd ≤ 6.3ns at 3.3V), IOFF leakage specs (±200μA at +125°C), Schmitt-trigger input hysteresis (ΔVT up to 1.40V), and package-specific thermal resistance (θJA = 371°C/W for SOT363).

Technical Context

The 74LVC1G58DW-7 implements a 3-input truth table with eight possible output states, enabling user-selectable logic functions without external components. Its input structure includes Schmitt-trigger action, resulting in hysteresis (ΔVT = 0.32–1.40V depending on VCC), which improves noise immunity in noisy digital environments.

IOFF circuitry actively disables the output during power-down, limiting backflow current to ±200μA at +125°C. The device supports mixed-voltage operation: 5.5V-tolerant inputs allow interfacing with legacy 5V systems while powered from as low as 1.65V, making it suitable for battery-powered and multi-rail embedded designs.

FAQ

Can the 74LVC1G58DW-7 be used as a level shifter between 1.8V and 5V domains?

Yes. Its 5.5V-tolerant inputs accept 0–5.5V signals regardless of VCC voltage (1.65–5.5V), and its push-pull output swings rail-to-rail. When powered from 1.8V, it reliably translates 5V inputs to 1.8V logic levels without external resistors or diodes - confirmed by VIH/VIL specs and IOFF behavior during power transitions.

What logic functions does the 74LVC1G58DW-7 support, and how are they selected?

It supports AND, OR, NAND, NOR, XOR, inverter, and non-inverting buffer functions. Selection is achieved by hardwiring the three inputs (IN0, IN1, IN2) to VCC or GND per the Function Selection Table in DS35126. No external programming or clock is needed - configuration is static and determined at power-up based on input bias states.

Does the 74LVC1G58DW-7 have Schmitt-trigger inputs, and what is their impact?

Yes - all three inputs feature Schmitt-trigger action with hysteresis (ΔVT = 0.32–1.40V depending on VCC). This increases noise margin on slow or noisy signals, preventing multiple transitions due to ringing or EMI. It is especially valuable in mechanical switch debouncing, encoder interfacing, and long-trace board-level signaling.

How does IOFF protect the device during partial power-down?

When VCC = 0V, the IOFF circuit disables the output stage and isolates the Y pin electrically from both VCC and GND. Measured IOFF leakage is ≤±200μA at +125°C, preventing damaging back-current flow into a powered bus or adjacent ICs - critical for hot-swap, battery-backed, or modular system architectures.
