Diodes Incorporated 74LVC07AS14-13

Overview

74LVC07AS14-13 from Diodes Incorporated is a hex buffer IC with six independent open-drain outputs, designed for level-shifting and wired-logic interfacing in mixed-voltage systems. It operates from 1.65V to 5.5V, tolerates 5.5V inputs, sinks up to 24mA at 3.3V, and supports partial power-down via IOFF-enabling safe isolation during system sleep states in PC I/O expansion and peripheral control.

For engineers reviewing the 74LVC07AS14-13 datasheet, 74LVC07AS14-13 pinout, 74LVC07AS14-13 application, or 74LVC07AS14-13 equivalent, key selection criteria include open-drain drive strength, IOFF-enabled backflow prevention, 5.5V-tolerant inputs, and SO-14 package compatibility with legacy 74-series footprints.

Technical Context

This device implements six non-inverting buffers with open-drain outputs, enabling active-low wired-OR and active-high wired-AND logic configurations. Each channel features 5.5V-tolerant inputs and IOFF circuitry that disables output leakage when VCC = 0V-critical for hot-swap and multi-rail power sequencing.

Propagation delay ranges from 1.7ns (min) to 7.6ns (max), depending on supply voltage and temperature; output low voltage is specified down to 0.2V at 100μA and 0.55V at 24mA (3.0V VCC), ensuring reliable TTL/CMOS interface across 1.65–5.5V operation.

FAQ

What is the maximum sink current per output at 1.8V supply?

At VCC = 1.8V, the 74LVC07AS14-13 guarantees 4mA sink current with VOL ≤ 0.45V (per datasheet Table 6). This is sufficient for driving small-signal MOSFET gates or low-current indicator LEDs, but not high-brightness displays or relay coils.

Can unused inputs be left floating?

No-unused inputs must be tied to either VCC or GND. Floating CMOS inputs cause increased ICC current, potential oscillation, and ESD vulnerability. The datasheet explicitly states: "Unused inputs should be held at VCC or Ground" under Recommended Operating Conditions.

Does this device support I²C bus arbitration?

Yes-its open-drain outputs and 5.5V-tolerant inputs make it suitable for I²C bus extension and arbitration. When used as a repeater, it preserves the wired-AND behavior required for multi-master arbitration, provided external pull-ups match bus voltage and capacitance limits.

Is the SO-14 package lead-free and RoHS compliant?

Yes-the 74LVC07AS14-13 is fully RoHS 3 compliant (2015/863/EU), lead-free, halogen-free, and antimony-free per Diodes' "Green" definition (<900ppm Br, <900ppm Cl, <1000ppm Sb), with no purposely added lead and certified to IATF 16949 manufacturing standards.
