Diodes Incorporated 74LV07AS14-13

Overview

74LV07AS14-13 from Diodes Incorporated is a hex buffer IC with six independent open-drain outputs, designed for voltage translation and signal isolation in mixed-voltage systems. It operates from 2.0V to 5.5V, accepts 5.5V-tolerant inputs, sinks up to 12mA at V_CC = 4.5V, features I_OFF for partial power-down protection, and includes Schmitt-trigger inputs for noise immunity - deployed in PC peripheral interfaces and set-top box I/O expansion.

For engineers reviewing the 74LV07AS14-13 datasheet, 74LV07AS14-13 pinout, 74LV07AS14-13 application, or 74LV07AS14-13 equivalent, key selection criteria include open-drain drive capability, 5.5V input tolerance, I_OFF leakage performance, propagation delay across supply voltages (3.8–10.4 ns), and SO-14 package compatibility with legacy 74-series footprint layouts.

Technical Context

The 74LV07AS14-13 implements six non-inverting buffers with open-drain outputs, enabling wired-OR logic, level shifting between 3.3V and 5V domains, and bus driving with external pull-ups. Its I_OFF circuitry actively disables outputs during power-down, preventing back-current flow when V_CC = 0V while inputs remain biased at up to 5.5V.

All six channels feature Schmitt-trigger inputs with hysteresis (~0.3V at V_CC = 3.3V), ensuring robust noise rejection in noisy industrial control or consumer I/O environments. The device meets JESD22 ESD ratings: >2000V HBM, >1000V CDM, and >200V MM, and supports latch-up immunity per JESD78 Class I (>100mA).

FAQ

Can 74LV07AS14-13 drive a standard 5V TTL input directly?

Yes - its open-drain outputs can sink up to 12mA at V_CC = 4.5V, exceeding the 1.6mA minimum sink requirement for standard TTL inputs. When paired with a 5V pull-up resistor (e.g., 4.7kΩ), it delivers valid TTL logic LOW levels (<0.5V) and HIGH levels near 5V, satisfying both voltage and current thresholds.

Does 74LV07AS14-13 require external pull-up resistors on its outputs?

Yes - all six outputs are open-drain and lack internal pull-ups. Each output must be connected to an external pull-up resistor tied to the target logic rail (e.g., 3.3V or 5V). Typical values range from 2.2kΩ to 10kΩ, selected based on rise time requirements and bus capacitance.

What is the maximum operating temperature for continuous use?

The 74LV07AS14-13 is rated for continuous operation from –40°C to +125°C ambient temperature. Its junction temperature limit is +150°C, and thermal resistance (R_θJA) for SO-14 is 110°C/W - meaning it sustains full performance in industrial enclosures without forced airflow when power dissipation remains below ~4.5mW per gate.

How does I_OFF protect the device during partial power-down?

I_OFF disables all outputs when V_CC drops below ~0.8V, blocking current flow from powered inputs into the unpowered V_CC rail. Measured I_OFF leakage is ≤5μA across –40°C to +125°C, preventing damage to upstream drivers and avoiding unintended logic states during brown-out or hot-swap transitions.
