Diodes Incorporated 74LVC1G58FZ4-7

Overview

74LVC1G58FZ4-7 from Diodes Incorporated is a single 3-input configurable multiple-function logic gate in X2-DFN1410-6 package, supporting AND, OR, NAND, NOR, XOR, inverter, and buffer functions via input pattern selection. 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 mixed-voltage embedded interfaces.

For engineers reviewing the 74LVC1G58FZ4-7 datasheet, 74LVC1G58FZ4-7 pinout, 74LVC1G58FZ4-7 application, or 74LVC1G58FZ4-7 equivalent, key selection criteria include its programmable logic function mapping, Schmitt-trigger input hysteresis (0.32–1.40V), IOFF-enabled power-down leakage (<±200μA), and compatibility with 1.65–5.5V supply domains in space-constrained designs.

Technical Context

The 74LVC1G58 implements a fixed 3-input combinational logic block whose output Y is determined by all eight possible IN2/IN1/IN0 combinations, enabling user-defined Boolean functions without external configuration pins. Its inputs exhibit Schmitt-trigger action, providing noise immunity with hysteresis ranging from 0.32V (at 3V) to 1.40V (at 5.5V).

IOFF circuitry actively disables the output during power-down, blocking reverse current flow when VCC = 0V while inputs or outputs remain biased up to 5.5V. Propagation delay is 0.7–6.4ns across 1.8–5.0V supply and –40°C to +125°C, with load-dependent timing (CL = 30/50pF).

FAQ

What logic functions can the 74LVC1G58FZ4-7 implement?

The 74LVC1G58FZ4-7 implements eight fixed Boolean outputs based on its three inputs (IN2/IN1/IN0), enabling user-selectable configurations for AND, OR, NAND, NOR, XOR, inverter, and non-inverting buffer functions. No external programming or configuration pins are needed - function selection is achieved solely by hardwiring inputs to VCC or GND per the datasheet's function selection table.

Does the 74LVC1G58FZ4-7 support true bidirectional operation?

No, the 74LVC1G58FZ4-7 has a unidirectional push-pull output (Y) and three dedicated inputs (IN0/IN1/IN2). It does not support bidirectional data flow or bus transceiver functionality. Its IOFF feature only disables the output driver during power-down - it does not convert the pin into a high-impedance input.

Can unused inputs be left floating?

No. Unused inputs must be tied to either VCC or GND per the datasheet recommendation (Note 5). Floating inputs may cause excessive ICC current, unpredictable output states due to noise coupling, or increased EMI emissions. The device's Schmitt-trigger inputs do not eliminate the need for defined DC bias - they only improve noise rejection on properly terminated signals.

Is the 74LVC1G58FZ4-7 qualified for automotive applications?

The base 74LVC1G58FZ4-7 is not AEC-Q100 qualified. However, Diodes Incorporated offers automotive-grade versions (e.g., 74LVC1G58FZ4-7Q) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation.
