Texas Instruments SN74LVC07APWRG3

Overview

SN74LVC07APWRG3 from Texas Instruments is a hex buffer and driver IC with six independent open-drain outputs, designed for 1.65 V to 5.5 V operation. It delivers 24 mA sink current per output at 3.3 V, supports 5.5-V-tolerant inputs/outputs, and achieves 2.6 ns propagation delay at 5 V. It is used in level translation, wired-OR logic, and LED driving in mixed-voltage digital systems.

For engineers reviewing the SN74LVC07APWRG3 datasheet, SN74LVC07APWRG3 pinout, SN74LVC07APWRG3 application, or SN74LVC07APWRG3 equivalent, key selection criteria include open-drain drive strength, Ioff-enabled partial-power-down capability, voltage translation across 1.65–5.5 V rails, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The SN74LVC07APWRG3 implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at VCC = 3 V and 5.5 V on input/output pins regardless of VCC level. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-current during live insertion or partial power-down.

This device operates across –40°C to +125°C and supports mixed-signal interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V logic families. Propagation delay remains ≤3.1 ns over full temperature range at 5 V, and input hysteresis is not specified - inputs are standard CMOS with VIH/VIL thresholds scaling with VCC.

FAQ

What is the maximum sink current per output of the SN74LVC07APWRG3?

The SN74LVC07APWRG3 supports up to 24 mA sink current per output at VCC = 3 V, as specified in the Electrical Characteristics table under IOL test conditions. This rating holds across the full operating temperature range (–40°C to +125°C) and enables direct driving of LEDs, optocouplers, or TTL loads without external amplification. The SN74LVC07APWRG3 maintains this performance while remaining compatible with 1.65–5.5 V supply rails.

Does the SN74LVC07APWRG3 support level translation between different voltage domains?

Yes, the SN74LVC07APWRG3 supports bidirectional level translation: its inputs accept voltages up to 5.5 V regardless of VCC, and its open-drain outputs tolerate up to 5.5 V when pulled up externally. For example, with VCC = 1.8 V, it can accept 3.3-V or 5-V inputs and drive a 5-V pull-up network - making the SN74LVC07APWRG3 ideal for bridging legacy and modern logic families without additional translators.

Can the SN74LVC07APWRG3 be used in hot-swap applications?

Yes, the SN74LVC07APWRG3 includes Ioff circuitry that disables outputs when VCC = 0 V, limiting off-state leakage to ±10 µA. This feature prevents damaging back-current flow during live insertion or removal from powered systems - a requirement for compliant hot-swap implementations. The SN74LVC07APWRG3 thus supports safe integration into modular backplanes and field-replaceable units without auxiliary protection circuitry.

What is the propagation delay of the SN74LVC07APWRG3 at 3.3 V?

At VCC = 3.3 V and TA = –40°C to +85°C, the SN74LVC07APWRG3 exhibits a maximum propagation delay (tpd) of 3.6 ns, as documented in the Switching Characteristics table. At the extended temperature range (–40°C to +125°C), the max tpd increases to 4.1 ns. These values reflect worst-case A→Y timing under CL = 30 pF load and ensure timing predictability in high-speed control and data-path applications using the SN74LVC07APWRG3.

Is a bypass capacitor required for the SN74LVC07APWRG3, and what value is recommended?

Yes, a bypass capacitor is mandatory for stable operation of the SN74LVC07APWRG3. TI recommends a 0.1 µF ceramic capacitor placed as close as possible to the VCC pin (Pin 14) and GND (Pin 7). For systems with noise-sensitive analog sections or high-frequency switching, paralleling a 1 µF capacitor improves broadband suppression. This decoupling ensures clean power delivery and prevents supply-induced jitter or false triggering - essential for reliable SN74LVC07APWRG3 performance in noise-prone environments.
