Diodes Incorporated 74LVC1G97FZ4-7

Overview

74LVC1G97FZ4-7 from Diodes Incorporated is a single three-input configurable multiple-function logic gate in X2-DFN1410-6 package, supporting MUX, AND, OR, NAND, NOR, inverter, and non-inverting buffer functions via 3-bit input pattern selection. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, features 5.5V-tolerant inputs, and includes IOFF circuitry for partial power-down protection. It is used in voltage level shifting and power-down signal isolation in portable consumer electronics.

For engineers reviewing the 74LVC1G97FZ4-7 datasheet, 74LVC1G97FZ4-7 pinout, 74LVC1G97FZ4-7 application, or 74LVC1G97FZ4-7 equivalent, this device serves as a space-constrained, mixed-voltage compatible logic configurator with Schmitt-trigger input hysteresis, low ICC (≤4μA), and industrial temperature range support (–40°C to +125°C).

Technical Context

The 74LVC1G97FZ4-7 implements combinational logic via an internal 3-to-1 multiplexer architecture controlled by IN0, IN1, and IN2, enabling eight distinct truth-table outputs. Its inputs exhibit Schmitt-trigger action with hysteresis (ΔVT = 0.30–1.40V depending on VCC), improving noise immunity in noisy digital environments.

IOFF functionality disables output during power-down to prevent backflow current, while 5.5V-tolerant inputs allow interfacing with higher-voltage logic without level shifters. Propagation delay ranges from 0.7ns (min) to 6.4ns (max) at VCC = 5V and TA = –40°C to +125°C with CL = 50pF.

FAQ

What logic functions can the 74LVC1G97FZ4-7 implement?

The 74LVC1G97FZ4-7 implements eight logic functions determined by its three input pins (IN0–IN2): 2-to-1 multiplexer, 2-input AND, OR, NAND, NOR (with one or both inputs inverted), inverter, and non-inverting buffer. The specific function is selected by the binary combination applied to IN0, IN1, and IN2 per the documented function table-not programmable via serial interface or register writes.

Does the 74LVC1G97FZ4-7 support true bidirectional operation?

No-the 74LVC1G97FZ4-7 has a unidirectional push-pull output (Y) and three dedicated input pins (IN0–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 enable reverse signal propagation.

Can unused inputs be left floating?

No-unused inputs must be externally tied to either VCC or GND per datasheet Note 6. Floating inputs may cause increased ICC, unpredictable output states due to Schmitt-trigger metastability, or excessive power consumption. For example, if configuring as a 2-input AND gate, the third input should be hard-wired to logic HIGH to avoid undefined behavior.

Is the X2-DFN1410-6 package compatible with standard reflow profiles?

Yes-the X2-DFN1410-6 package is rated for moisture sensitivity level 1 (MSL-1) per J-STD-020 and supports standard Pb-free reflow profiles (peak ≤260°C). Its matte tin-plated terminals meet MIL-STD-202 Method 208 solderability requirements, and recommended pad layout dimensions are provided in the datasheet for reliable solder joint formation and AOI compatibility.
