Product details
Overview
74VHCV07FT from Toshiba Electronic Devices & Storage Corporation is a hex Schmitt buffer with open-drain outputs, fabricated in silicon gate CMOS technology. It delivers 3.8 ns typical propagation delay at 5.0 V, supports 1.8–5.5 V supply range, and operates across –40°C to +125°C - enabling robust signal conditioning in automotive body control modules.
For engineers reviewing the 74VHCV07FT datasheet, 74VHCV07FT pinout, 74VHCV07FT application, or 74VHCV07FT equivalent, this device serves as a high-speed, low-power, AEC-Q100 qualified logic buffer for noise-immune level translation, bus driving, and slow-edge signal cleanup in harsh-temperature embedded systems.
Technical Context
The 74VHCV07FT integrates six independent Schmitt-trigger input buffers, each with hysteresis (VP = 1.65 V, VN = 1.10 V typ. at VCC = 5.0 V) to reject noise on slowly varying signals. Its open-drain N-channel MOS output stage supports 16 mA sink current at 4.5 V and tolerates up to 5.5 V on outputs regardless of VCC.
All inputs and outputs feature overvoltage protection (–0.5 V to 7.0 V), power-down protection, and rail-to-rail input voltage tolerance - enabling safe interfacing between mismatched supply domains, such as battery-backed circuits or mixed-voltage I²C/SPI buses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Hex Schmitt-trigger buffer with open-drain outputs - enables wired-AND bus structures and level-shifting without pull-up conflicts. |
| Propagation Delay | 3.8 ns (typ.) at VCC = 5.0 V, CL = 50 pF - supports >100 MHz signal edge rates in timing-critical interfaces. |
| Supply Voltage Range | 1.8 V to 5.5 V - allows direct interface with 1.8 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Sink Current | 16 mA (min.) at VCC = 4.5 V - drives standard LED loads or 50 Ω transmission lines with controlled rise/fall times. |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Rev. H for under-hood automotive applications. |
| Input Hysteresis | 0.55 V (typ., VH = VP – VN at VCC = 5.0 V) - rejects up to ±275 mV of common-mode noise on slow-rising sensor signals. |
| Quiescent Current | 2.0 µA (max.) at TA = 25°C - enables always-on monitoring in low-power wake-up circuits. |
Pinout & Package
TSSOP14B package: 14-pin thin shrink small outline package, 0.65 mm pitch, 5.0 mm × 4.4 mm footprint, 1.2 mm max height, 0.054 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (A1–A6) | Schmitt-trigger buffered inputs - accept slow edges (dt/dv ≤ 20 ms/V) and reject noise via hysteresis. |
| 2, 4, 6, 10, 12, 14 | Open-Drain Output (Y1–Y6) | N-channel MOS drain terminals - require external pull-up; support voltage translation up to 5.5 V independent of VCC. |
| 7 | GND | Ground reference for all internal circuitry and ESD protection networks. |
| 14 | VCC | Positive supply for internal logic - powers input hysteresis and output driver; tolerant of 1.8–5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 qualified | Complies with Rev. H stress test requirements - validated for automotive-grade reliability in temperature cycling, HTOL, and ESD. |
| Rail-to-rail input tolerance | Accepts –0.5 V to 7.0 V on inputs regardless of VCC - eliminates need for clamping diodes in mixed-supply systems. |
| Power-down protection | Prevents back-driving and latch-up when VCC = 0 V - ensures safe hot-plug operation in modular subsystems. |
| PIN-compatible with 74AC/HC/AHC/LV 07 series | Drop-in replacement for legacy hex buffers - no PCB redesign required for upgrade paths. |
| Low ICC at 25°C | 2.0 µA max quiescent current - reduces standby power in battery-powered telematics and gateway ECUs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV07APWR | Lower max operating temperature (–40°C to +125°C not guaranteed; rated only to +85°C); no AEC-Q100 qualification; 4.5 ns tPD at 3.3 V. | Not suitable for under-hood automotive use; acceptable for industrial control panels with ambient <85°C. | Select when cost sensitivity outweighs automotive qualification and extended temperature needs. |
| 74LVC1G07GW,125 | Single-channel (not hex); smaller XSON6 package; 3.7 ns tPD at 3.3 V; same 1.65–5.5 V VCC range. | Requires six separate packages for full functionality; better for space-constrained, low-channel-count designs. | Choose for miniaturized IoT sensor nodes where board area is critical and channel count is low. |
Compared with SN74LV07APWR and 74LVC1G07GW,125, the 74VHCV07FT uniquely combines AEC-Q100 qualification, full –40°C to +125°C operation, and hex-channel integration in TSSOP14B - making it the only drop-in solution for automotive body electronics requiring guaranteed performance across full temperature range.

FAQ
What is the maximum input voltage rating for 74VHCV07FT, and how does it benefit system design?
The 74VHCV07FT supports input voltages from –0.5 V to 7.0 V, independent of VCC. This rail-to-rail input tolerance allows direct connection to higher-voltage peripherals (e.g., 5.5 V sensors or battery-backed circuits) without external clamping diodes or level shifters. In automotive applications, this protects against load-dump transients and simplifies interface design in mixed-supply domains - a key advantage confirmed in Toshiba's Absolute Maximum Ratings table.
Does 74VHCV07FT support true open-drain operation, and what is its minimum guaranteed sink current?
Yes, the 74VHCV07FT features true open-drain N-channel MOS outputs. Its datasheet guarantees a minimum sink current of 16 mA at VCC = 4.5 V and VOL ≤ 0.55 V, verified across –40°C to +125°C. This enables reliable driving of LEDs, pull-up resistors for I²C buses, or gate control of external MOSFETs - directly supporting wired-AND logic and voltage-level translation.
Is 74VHCV07FT pin-compatible with legacy 74-series hex buffers like 74HC07?
Yes, the 74VHCV07FT is explicitly stated as pin- and function-compatible with 74AC/HC/AHC/LV 07-type devices. Its TSSOP14B footprint matches industry-standard 14-pin logic packages, and truth table behavior (non-inverting Schmitt buffer with open-drain output) aligns exactly with the 74x07 family - enabling drop-in replacement without layout changes.
What is the hysteresis voltage of 74VHCV07FT, and why is it important for sensor interfacing?
The 74VHCV07FT provides typical hysteresis of 0.55 V (VP – VN = 1.65 V – 1.10 V at VCC = 5.0 V), ensuring robust rejection of noise on slow-moving signals. For example, in door position sensing or rotary encoder debouncing, this hysteresis prevents multiple toggles due to contact bounce or EMI - delivering clean, chatter-free digital transitions to the host MCU.
How does the AEC-Q100 qualification of 74VHCV07FT impact its use in automotive applications?
The 74VHCV07FT is fully compliant with AEC-Q100 Rev. H, covering stress tests including temperature cycling, high-temperature operating life, and ESD. This qualification validates its suitability for automotive body electronics (e.g., lighting control, seat modules, HVAC actuators) where reliability over 15+ years and operation at 125°C ambient are required - a distinction not shared by generic logic buffers.
