Texas Instruments SN74LVC07ANS

Overview

SN74LVC07ANS from onsemi is a low-voltage CMOS hex buffer with six independent open-drain outputs, operating from 1.2 V to 5.5 V supply, featuring 5.5 V-tolerant inputs, 24 mA output sink capability at 3.0 V, and near-zero static supply current (10 µA). It enables wired-AND logic, level translation, and active-low OR functions in mixed-voltage interface circuits.

For engineers reviewing the SN74LVC07ANS datasheet, SN74LVC07ANS pinout, SN74LVC07ANS application, or SN74LVC07ANS equivalent, key selection criteria include open-drain drive strength, input voltage tolerance across VCC ranges, propagation delay consistency from 1.2 V to 5.5 V, and SOIC-14 package compatibility with legacy 5 V systems.

Technical Context

The SN74LVC07ANS implements six identical non-inverting buffers with open-drain outputs, requiring external pull-up resistors to define HIGH-level output voltage. Its input structure supports LVTTL and LVCMOS logic families and withstands up to 5.5 V regardless of VCC, enabling safe interfacing with 5 V drivers while powered from 1.65–3.3 V rails.

Propagation delays are characterized across full VCC range: tpZL = 0.5–5.5 ns and tpLZ = 0.5–6.5 ns (−40°C to +85°C), with dynamic LOW peak/valley voltages specified at ±0.6–0.8 V under defined capacitive loads. Input leakage remains ≤±0.1 µA over temperature and voltage.

Key Specifications

Pinout & Package

SN74LVC07ANS is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package per case 751A, with 1.27 mm pitch, 8.55–8.75 mm body width, and 3.80–4.00 mm body length. Pin 1 is marked by a beveled corner or dot.

FAQ

What is the maximum input voltage rating for SN74LVC07ANS?

The SN74LVC07ANS supports DC input voltages from −0.5 V to +6.5 V, independent of VCC. This allows safe interfacing with 5 V logic sources even when powered from 1.2 V to 3.3 V supplies-no external clamping diodes or level shifters are needed for such connections.

Can SN74LVC07ANS drive a standard red LED directly?

Yes, SN74LVC07ANS can drive a standard red LED directly: at VCC = 3.0 V, it sinks up to 24 mA per output, sufficient for typical 2–20 mA LED currents. An external current-limiting resistor must be used between the LED anode and the positive rail, with the cathode connected to an SN74LVC07ANS output pin.

Does SN74LVC07ANS have internal pull-up resistors on its outputs?

No, SN74LVC07ANS has true open-drain outputs with no internal pull-up resistors. Each output requires an external pull-up resistor to the desired HIGH-level voltage (e.g., 3.3 V or 5 V) to establish a valid logic HIGH state. The value depends on speed and load-typically 1–10 kΩ.

What is the operating temperature range for SN74LVC07ANS?

The SN74LVC07ANS is rated for operation from −40°C to +125°C ambient temperature. This extended industrial range supports deployment in harsh environments such as factory automation controllers, motor drives, and outdoor infrastructure equipment.

Is SN74LVC07ANS pin-compatible with older 74LS07 devices?

No, SN74LVC07ANS is not pin-compatible with 74LS07: both are hex buffers with open-drain outputs, but 74LS07 uses a 14-pin DIP or SOIC package with identical pinout (A0–A5 on odd pins, O0–O5 on even pins, GND at pin 7, VCC at pin 14), so physical pin alignment matches-but electrical behavior differs significantly (e.g., 74LS07 requires 5 V only and lacks 5 V-tolerant inputs).
