Diodes Incorporated 74LV00AS14-13

Overview

74LV00AS14-13 from Diodes Incorporated is a quad 2-input NAND gate IC in SO-14 package, operating from 2.0V to 5.5V supply, with 5.5V-tolerant inputs, IOFF-enabled partial power-down protection, and Schmitt-trigger inputs for noise immunity. It delivers 12mA output drive at 4.5V and supports voltage translation between 3.3V and 5V logic domains in mixed-supply systems.

For engineers reviewing the 74LV00AS14-13 datasheet, 74LV00AS14-13 pinout, 74LV00AS14-13 application, or 74LV00AS14-13 equivalent, key selection criteria include input voltage tolerance (5.5V), IOFF leakage (<5μA), propagation delay (3.6–7.5ns at 5V), output drive capability (±12mA), and SO-14 thermal and PCB layout compatibility.

Technical Context

This device implements four independent NAND logic functions (Y = A·B) using low-voltage CMOS technology. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and bus isolation in multi-rail systems.

All inputs feature Schmitt-trigger action with hysteresis (~0.3×VCC), ensuring robust noise rejection in noisy environments. Input voltage range extends to 5.5V regardless of VCC, allowing direct interfacing with higher-voltage peripherals without level shifters.

FAQ

Can 74LV00AS14-13 be used with a 2.0V supply while interfacing to 5V signals?

Yes. Its inputs tolerate up to 5.5V regardless of VCC, and its output VOH remains ≥VCC−0.1V. At 2.0V supply, outputs swing 1.9V high-sufficient to drive 2.5V or higher logic thresholds. This enables true bidirectional voltage translation without external components.

What happens to the outputs during power-down (VCC = 0V)?

When VCC drops to 0V, the IOFF circuit activates automatically, disabling all outputs and limiting leakage current to <5μA. This prevents reverse current flow from powered inputs or buses into the unpowered IC, protecting both the device and connected circuitry from damage or unintended behavior.

Does the SO-14 package support reflow soldering per JEDEC J-STD-020?

Yes. The SO-14 package for 74LV00AS14-13 is rated for standard lead-free reflow profiles (peak 260°C, 10-second duration). Its thermal mass and lead finish comply with JEDEC J-STD-020D.3, and Diodes Inc. provides full package outline and pad layout drawings (AP02001/AP02002) for verified PCB design.

How does Schmitt-trigger action improve performance over standard TTL/CMOS inputs?

Schmitt-trigger inputs provide hysteresis (~0.3×VCC), meaning VIH and VIL differ by ~0.6V at 2.0V supply. This rejects noise spikes and slow-rising edges that would cause multiple transitions on standard inputs-critical for mechanical switches, long traces, or unshielded sensor lines where signal integrity cannot be guaranteed.
