Product details
Overview
SN74LVC07ANSR 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, achieves 2.6 ns max propagation delay at 5 V, and features Ioff for live insertion and partial-power-down protection. It is used in level translation and wired-OR logic in consumer audio and SSD power control circuits.
For engineers reviewing the SN74LVC07ANSR datasheet, SN74LVC07ANSR pinout, SN74LVC07ANSR application, or SN74LVC07ANSR equivalent, key selection criteria include open-drain drive strength (24 mA), wide VCC range (1.65–5.5 V), 5.5-V input/output tolerance, Ioff-enabled power sequencing, and SO package compatibility with legacy 14-pin through-hole footprints.
Technical Context
The SN74LVC07ANSR implements six identical CMOS buffer stages, each with an open-drain output stage capable of sinking up to 24 mA at 3.3 V while maintaining VOL ≤ 0.55 V. Its Ioff circuitry actively disables all outputs when VCC = 0 V, blocking back-drive current and enabling hot-swap capability in mixed-voltage systems.
Inputs accept voltages up to 5.5 V regardless of VCC, allowing direct interfacing with 5-V TTL or LVTTL sources across the full 1.65–5.5 V supply range. Propagation delay is specified from 1 ns (1.8 V, –40°C to 85°C) to 3.1 ns (5 V, –40°C to 125°C), supporting reliable operation up to 100 MHz in buffered signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains. |
| Output Sink Current | 24 mA per channel at 3 V - Sufficient to drive multiple CMOS inputs or small LEDs without external pull-ups. |
| Propagation Delay | 2.6 ns max at 5 V - Supports high-speed signal buffering in timing-critical digital interfaces. |
| Input/Output Voltage Tolerance | Up to 5.5 V - Allows safe interfacing with higher-voltage controllers while powered from lower VCC. |
| Ioff Current | ±10 µA at 0 V VCC - Prevents damaging back-current during power sequencing or hot-plug events. |

IC Role / Device Role / Timing Role: Open-drain outputs interface with shared system reset bus; wired-OR configuration supports multi-source assertion. Use Value: 24 mA sink capability ensures fast, clean transitions on heavily loaded reset lines with multiple downstream devices. |
| Industrial Sensor Interface | Legacy Bus Signal Conditioning |
|
Use Scenario: Buffering and translating analog-to-digital converter (ADC) busy signals from 5-V sensors to 1.8-V FPGA inputs.

IC Role / Device Role / Timing Role: Provides six independent, high-drive open-drain drivers for bidirectional bus arbitration signals. Use Value: 2.6 ns max tpd ensures sub-400 MHz timing margin for 25-MHz parallel bus cycles with setup/hold compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex open-drain buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC06ANSR | Inverting logic function (buffer outputs complemented); otherwise identical electrical specs and pinout. | Requires logic inversion in signal path; unsuitable where non-inverting polarity is mandatory. | Select SN74LVC06ANSR only when system-level logic requires inverted enable/reset signals. |
| 74LVC07APW | TSSOP-14 package (5.00 mm × 4.40 mm); same electrical performance but smaller footprint and surface-mount only. | Not compatible with through-hole SO sockets; requires PCB redesign for assembly. | Choose 74LVC07APW for space-constrained designs where automated SMT assembly is available. |
Compared with SN74LVC07ANSR, SN74LVC06ANSR offers identical drive and voltage specs but inverts logic polarity-critical for reset generation where active-low assertion must remain non-inverted. 74LVC07APW matches functionality in a smaller TSSOP package, trading socket compatibility for board area savings.

FAQ
What is the maximum sink current per output of the SN74LVC07ANSR?
The SN74LVC07ANSR supports a maximum sink current of 24 mA per output at VCC = 3 V, with VOL ≤ 0.55 V under that condition. This rating holds across the full operating temperature range (–40°C to +125°C) and is validated per TI's switching characteristics test conditions. Exceeding 24 mA risks violating VOL specifications and may impact reliability.
Can the SN74LVC07ANSR interface between a 5-V microcontroller and a 1.8-V FPGA?
Yes, the SN74LVC07ANSR can safely interface a 5-V microcontroller to a 1.8-V FPGA. Its inputs tolerate up to 5.5 V regardless of VCC, and its open-drain outputs can be pulled up to 1.8 V. When VCC = 1.8 V, the device operates within spec and maintains 5.5-V input tolerance - enabling robust level translation without external components.
Does the SN74LVC07ANSR support hot-swap or live-insertion applications?
Yes, the SN74LVC07ANSR supports hot-swap applications via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all outputs, limiting off-state current to ±10 µA and preventing back-drive current from live I/O lines. This behavior is explicitly characterized in TI's datasheet Section 6.5 and qualifies the SN74LVC07ANSR for use in modular backplane and pluggable module designs.
What is the recommended bypass capacitor for the SN74LVC07ANSR VCC pin?
Texas Instruments recommends a 0.1 µF ceramic bypass capacitor placed as close as possible to the VCC pin (Pin 14) of the SN74LVC07ANSR. For systems with multiple power domains or high noise sensitivity, paralleling a 1 µF capacitor is acceptable. The datasheet specifies this in Section 10 and emphasizes low-inductance placement to suppress supply transients during fast output transitions.
Is the SN74LVC07ANSR pin-compatible with other packages in the SN74LVC07A family?
No, the SN74LVC07ANSR (SO-14) is not mechanically pin-compatible with other SN74LVC07A variants like the TSSOP-14 (PW) or VQFN-14 (RGY), though all share identical pin functions and numbering. The SO package has 1.27 mm lead pitch and through-hole footprint, while PW and RGY use finer pitches and surface-mount land patterns. Electrical and functional compatibility exists, but PCB layout must match the specific package.
