Product details
Overview
MC74VHC1GT04DF1G from onsemi is a single-channel CMOS inverting buffer with TTL-compatible inputs and full 5.0 V CMOS output swing, designed for logic-level translation between 1.8 V/3.0 V and 3.0 V/5.0 V domains. It delivers 3.8 ns typical propagation delay at 5.0 V, consumes ≤1 µA quiescent current, and supports −55°C to +125°C operation in SC-88A (SOT-353) package.
For engineers reviewing the MC74VHC1GT04DF1G datasheet, pinout, applications, or equivalent options, key selection criteria include input overvoltage tolerance up to 7.0 V, power-down protection on I/O, balanced tPLH/tPHL delays, and compatibility with LSTTL, VHC, and other standard logic families.
Technical Context
The MC74VHC1GT04DF1G implements a three-stage CMOS inverter architecture with buffered output for high noise immunity. Its input structure tolerates up to 7.0 V regardless of VCC, enabling robust level-shifting without external components.
It features dual-rail protection: inputs remain safe during VCC = 0 V conditions, and outputs are protected against back-driving when VCC is unpowered. This supports hot-insertion and battery-backup scenarios in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 3.0 V to 5.5 V - enables operation across 3.3 V and 5 V systems without level-shifters |
| tPD (Typ) | 3.8 ns at VCC = 5.0 V, CL = 50 pF - supports >100 MHz signal integrity in timing-critical paths |
| VIH/VIL | 2.0 V / 0.8 V at VCC = 5.0 V - ensures reliable recognition of LSTTL logic levels |
| VOH/VOL | >0.8 VCC / <0.1 VCC at ±4 mA - guarantees rail-to-rail CMOS-compatible output drive |
| Input Overvoltage | −0.5 V to +7.0 V - allows direct interfacing of 5 V outputs to 3 V or 1.8 V supplies |
| ICC (Max) | 1.0 µA at TA = 25°C - enables ultra-low-power standby in battery-operated devices |
| Operating Temp | −55°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
MC74VHC1GT04DF1G is housed in a Pb-free SC-88A (SOT-353) 5-pin surface-mount package measuring 2.20 × 1.35 × 1.10 mm, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and I/O; required for stable logic thresholds and ESD protection path |
| 2 | NC | No-connect terminal - must be left floating or grounded per layout best practices; no internal connection |
| 3 | IN A | Inverting input - accepts TTL- or CMOS-level signals; withstands up to 7.0 V independent of VCC |
| 4 | VCC | Positive supply rail - powers internal logic stages and output driver; supports 3.0–5.5 V operation |
| 5 | OUT Y | Inverted output - provides full-swing CMOS output with ±4 mA drive capability and 0.1 VCC VOL |
Key Features
| Feature | Design Value |
|---|---|
| Input Overvoltage Tolerance | 7.0 V absolute max on IN A - eliminates need for external clamping diodes in mixed-supply interfaces |
| Power-Down Protection | Safe I/O operation with VCC = 0 V - prevents latch-up or damage during partial power sequencing |
| Propagation Delay Matching | tPLH ≈ tPHL (≤10% skew at 5 V) - ensures symmetrical rise/fall timing critical for clock buffering |
| Pb-Free SC-88A Package | RoHS-compliant 5-pin SOT-353 footprint - compatible with standard reflow profiles and automated assembly |
| ESD Robustness | Human Body Model >1500 V - reduces field failure risk in handling and board-level integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverting buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Lower VCC min (1.65 V), higher ICC (10 µA), no 7 V input tolerance | Better suited for sub-3 V portable designs; lacks overvoltage safety for 5 V interface scenarios | Select when operating below 3.0 V or when ultra-low ICC is not required |
| 74AUP1G04GW,125 | Wider VCC range (0.8–3.6 V), lower CPD (3 pF), but max VCC = 3.6 V only | Optimized for battery-powered 1.8/2.5/3.3 V systems; incompatible with 5 V domains | Choose for energy-constrained IoT nodes where 5 V interoperability is unnecessary |
Compared with SN74LVC1G04DBVR and 74AUP1G04GW,125, the MC74VHC1GT04DF1G uniquely supports 5 V operation with 7 V input tolerance and sub-µA quiescent current-making it the only option among the three qualified for mixed 3.3 V/5 V industrial control interfaces requiring robust hot-swap behavior.

FAQ
What is the maximum input voltage the MC74VHC1GT04DF1G can tolerate regardless of VCC?
The MC74VHC1GT04DF1G supports an absolute maximum input voltage of −0.5 V to +7.0 V on its IN A pin, independent of the VCC supply level. This overvoltage tolerance enables safe interfacing between higher-voltage logic domains (e.g., 5 V) and lower-voltage systems (e.g., 3.3 V or 1.8 V) without external protection components. The specification is validated per JEDEC standards and confirmed in the device's Maximum Ratings table.
Does the MC74VHC1GT04DF1G support operation with VCC = 0 V?
Yes, the MC74VHC1GT04DF1G provides power-down protection: both input and output structures remain functional and non-damaging even when VCC = 0 V. This allows safe signal routing during partial power-down states, hot insertion of modules, or battery-backup scenarios. The input diode current limit is ±20 mA, and output protection holds for VOUT < GND or VOUT > VCC, as specified in the Absolute Maximum Ratings.
What is the propagation delay matching between tPLH and tPHL for the MC74VHC1GT04DF1G at 5.0 V?
At VCC = 5.0 V and CL = 50 pF, the MC74VHC1GT04DF1G exhibits tPLH = 3.8 ns (typ) and tPHL = 3.8 ns (typ), indicating balanced rise and fall propagation delays. The datasheet confirms "balanced propagation delays" as a key feature, and measured values across temperature show ≤10% skew - critical for minimizing duty-cycle distortion in clock-buffering applications.
Is the MC74VHC1GT04DF1G pin-compatible with other single-gate logic devices in SC-88A packages?
Yes, the MC74VHC1GT04DF1G uses the standard SC-88A (SOT-353) 5-pin footprint with pin 1 = GND, pin 2 = NC, pin 3 = IN A, pin 4 = VCC, pin 5 = OUT Y. It is functionally and physically pin-compatible with other VHC, LVC, and AUP single-gate logic devices in the same package, including SN74LVC1G04DBVR and 74AUP1G04GW,125 - though electrical specifications (e.g., VCC range, input tolerance) differ.
What is the guaranteed output drive strength of the MC74VHC1GT04DF1G at 3.3 V supply?
At VCC = 3.3 V, the MC74VHC1GT04DF1G guarantees VOH ≥ 2.58 V and VOL ≤ 0.36 V when driving ±4 mA loads, per DC Electrical Characteristics. This ensures robust noise margins (>0.7 V) against 3.3 V LVTTL and LVCMOS receivers, and supports fan-out of at least two standard CMOS inputs under worst-case temperature and voltage conditions.
