Diodes Incorporated 74LV00AT14-13

Overview

74LV00AT14-13 from Diodes Incorporated is a quad 2-input NAND gate IC in TSSOP-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. 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 74LV00AT14-13 datasheet, 74LV00AT14-13 pinout, 74LV00AT14-13 application, or 74LV00AT14-13 equivalent, key selection criteria include input voltage tolerance, IOFF leakage (<5μA), propagation delay (3.6–7.5ns at 5V), output drive capability, and TSSOP-14 thermal and board-space advantages over SOIC.

Technical Context

This device implements four independent NAND gates with push-pull CMOS outputs and Schmitt-trigger inputs for noise immunity. Its IOFF circuit disables outputs during power-down to prevent back-current flow, enabling safe hot-insertion and partial-power-down operation in multi-rail systems.

The logic function Y = A·B is realized with rail-to-rail input voltage range (–0.5V to +7.0V) and output swing limited only by VCC and GND. Input clamp current is rated ±20mA, and latch-up immunity exceeds 100mA per JESD78 Class I, supporting robust operation in industrial environments.

FAQ

What is the maximum allowable input voltage for 74LV00AT14-13 when VCC = 3.3V?

The absolute maximum input voltage is +7.0V, and the recommended operating input range is –0.5V to +5.5V regardless of VCC level. This allows safe connection of 5V signals to a 3.3V-powered device without external clamping or level-shifting circuitry, leveraging its 5.5V-tolerant input structure.

Does 74LV00AT14-13 support hot-swap or live-insertion scenarios?

Yes - the integrated IOFF circuit automatically disables outputs when VCC is near 0V, limiting back-current to <5μA. This prevents damage to upstream drivers or bus contention during insertion into a live backplane or hot-pluggable module, satisfying JEDEC-compliant partial power-down requirements.

Can unused inputs be left floating?

No - unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling. The datasheet explicitly requires termination to ensure stable operation and avoid excessive power consumption or EMI generation.

Is the TSSOP-14 package RoHS and halogen-free compliant?

Yes - the 74LV00AT14-13 is fully RoHS 2 compliant (2011/65/EU), lead-free, and halogen- and antimony-free ("Green" per Diodes' definition: Br+Cl <1500ppm, Sb <1000ppm). This meets IPC-1752A material declaration requirements for environmentally regulated electronics manufacturing.
