Diodes Incorporated 74LVC1G58FW4-7

Overview

74LVC1G58FW4-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in X2-DFN1010-6 package, supporting AND/OR/NAND/NOR/XOR/inverter/buffer functions via input pin configuration. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, features 5.1ns max propagation delay at 3.3V, and includes IOFF for partial power-down protection. It enables voltage-level shifting in mixed-voltage I/O interfaces on portable computing and consumer electronics PCBs.

For engineers reviewing the 74LVC1G58FW4-7 datasheet, 74LVC1G58FW4-7 pinout, 74LVC1G58FW4-7 application, or 74LVC1G58FW4-7 equivalent, this device serves as a space-constrained, low-power reconfigurable logic element where board real estate and supply flexibility are critical - especially in battery-powered devices requiring 1.65–5.5V operation and 5.5V-tolerant inputs.

Technical Context

The 74LVC1G58FW4-7 implements a programmable 3-input truth table (8 combinations) to emulate seven distinct logic functions without external components. Its Schmitt-trigger input hysteresis (min 0.30V at 1.65V, up to 1.40V at 5.5V) improves noise immunity in noisy signal environments.

IOFF circuitry actively disables outputs during power-down, blocking back-current flow when VCC = 0V while inputs remain at 5.5V - enabling safe hot-insertion and multi-rail isolation in systems with staggered power sequencing.

FAQ

What logic functions can the 74LVC1G58FW4-7 implement?

The 74LVC1G58FW4-7 implements seven logic functions via its three input pins: AND, OR, NAND, NOR, XOR, inverter, and non-inverting buffer. Each function corresponds to a specific combination of IN0, IN1, and IN2 connections to VCC or GND per the documented function selection table - no external programming or configuration registers are required.

Does the 74LVC1G58FW4-7 support partial power-down operation?

Yes - the device includes an IOFF circuit that disables the output stage when VCC = 0V, limiting leakage current to ±10μA (TA = –40°C to +85°C). This prevents back-current flow from live inputs into a powered-down system rail, satisfying JEDEC JESD78 Class II latch-up immunity and enabling safe multi-rail power sequencing.

Can the 74LVC1G58FW4-7 interface directly with 5V logic signals?

Yes - all inputs tolerate up to 5.5V regardless of VCC level (1.65V–5.5V), allowing direct connection to 5V TTL or CMOS outputs without external level-shifting components. The output remains compliant with the VCC rail, so driving 5V logic requires VCC = 5V; for 3.3V systems, it drives 3.3V-compatible loads only.

What is the thermal performance of the X2-DFN1010-6 package?

The X2-DFN1010-6 package has a junction-to-ambient thermal resistance (θJA) of 510°C/W under standard FR-4 PCB conditions (2oz copper, minimum recommended pad layout). At 24mA output drive and 3.3V supply, typical power dissipation is <15mW - resulting in negligible temperature rise (<8°C) in most handheld and sensor applications.
