Product details
Overview
MC74VHC1GT08DF1G from onsemi is a single 2-input AND gate with TTL-level input thresholds, designed for 2.0 V to 5.5 V operation. It delivers 3.5 ns typical propagation delay at 5 V, supports 8 mA output drive at 3.0 V, and features over-voltage tolerant inputs/outputs up to 5.5 V - enabling robust 3 V/5 V mixed-voltage interface applications in portable and industrial control systems.
For engineers reviewing the MC74VHC1GT08DF1G datasheet, pinout, applications, or equivalent options, key selection considerations include its TTL-compatible VIH/VIL thresholds (1.4 V/0.45 V at 3.0 V), IOFF partial power-down protection, SC-88A package footprint, and guaranteed operation from −55 °C to +125 °C.
Technical Context
The MC74VHC1GT08DF1G implements a single 2-input AND logic function using advanced VHC CMOS technology. Its TTL-level input thresholds (VIH = 1.4 V, VIL = 0.45 V at VCC = 3.0 V) ensure compatibility with legacy 5 V TTL outputs while operating from a 3 V supply. Input and output structures tolerate voltages up to 5.5 V independent of VCC, supporting level-shifting without external components.
It integrates IOFF circuitry that disables I/O leakage when VCC = 0 V, preventing back-powering in partial power-down states. The device is rated for −55 °C to +125 °C operation and meets AEC-Q100 Grade 1 requirements when ordered with the −Q suffix - though MC74VHC1GT08DF1G itself is the standard industrial-grade variant in SC-88A (Case 419A) packaging.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 5.5 V - enables direct use in both 3.3 V and 5 V systems without level shifters. |
| tPD (Typ) | 3.5 ns at VCC = 5.5 V, CL = 15 pF - supports high-speed digital timing in compact logic interfaces. |
| VIH / VIL | 1.4 V / 0.45 V at VCC = 3.0 V - TTL-compatible thresholds allow interfacing with legacy 5 V logic outputs. |
| IOL / IOH | 8 mA sink/source at VCC = 3.0 V - sufficient drive strength for fan-out to multiple CMOS inputs or small LEDs. |
| Input/Output Voltage Tolerance | Up to 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-supply domains. |
| IOFF Support | Active when VCC = 0 V - prevents current backflow during hot-swap or partial power-down sequences. |
| Operating Temperature | −55 °C to +125 °C - suitable for extended industrial and under-hood automotive environments. |
Pinout & Package
MC74VHC1GT08DF1G is packaged in SC-88A (Case 419A), a 5-pin, 2.1 mm × 2.0 mm surface-mount package with 0.65 mm pitch. Pin 1 is marked by a dot or beveled edge per JEDEC MO-178.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B (Input) | Second logic input; accepts TTL- or CMOS-level signals up to 5.5 V. |
| 2 | A (Input) | Primary logic input; electrically identical to Pin 1, fully over-voltage tolerant. |
| 3 | GND | Ground reference for logic and power; must be low-impedance for noise immunity. |
| 4 | Y (Output) | AND result (A • B); drives loads up to 8 mA while maintaining VOL ≤ 0.44 V at 3.0 V. |
| 5 | VCC | Positive supply rail; powers internal logic and enables IOFF behavior when at 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input thresholds | Ensures reliable recognition of 5 V TTL outputs (e.g., 74LS series) when powered from 3 V supplies. |
| Over-voltage tolerant I/O | Allows direct connection between 3 V logic and 5 V peripherals without external protection circuitry. |
| IOFF partial power-down | Blocks current flow through inputs/outputs when VCC = 0 V - critical for hot-plug and battery-backup systems. |
| SC-88A ultra-small footprint | 2.1 mm × 2.0 mm body size saves PCB area in space-constrained IoT sensors and wearables. |
| −55 °C to +125 °C operation | Validated performance across full industrial temperature range without derating. |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |
|---|---|

Use Value: SC-88A footprint minimizes PCB real estate; over-voltage tolerance protects against transient coupling during power ramp. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar single 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G08DBVR | CMOS-level inputs (VIH = 2.0 V at 3.3 V), slightly slower tPD (4.5 ns typ @ 3.3 V). | Best suited for pure 3.3 V systems; lacks native TTL threshold compatibility. | Select when interfacing exclusively with modern CMOS outputs and lower dynamic power is prioritized. |
| 74AUP1G08GW,125 | Ultra-low power (0.9 µA ICC), wider VCC range (0.8–3.6 V), but no over-voltage tolerance beyond VCC. | Optimized for sub-1 V logic and energy harvesting; not suitable for 5 V interface scenarios. | Choose for battery-critical applications where supply is strictly ≤3.6 V and external clamping is acceptable. |
Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1GT08DF1G uniquely balances TTL-level compatibility, 5.5 V over-voltage tolerance, and industrial temperature support - making it the preferred choice for mixed-voltage industrial and automotive subsystems requiring robustness without design compromises.

FAQ
What is the input threshold voltage of MC74VHC1GT08DF1G at 3.0 V supply?
The MC74VHC1GT08DF1G has TTL-level input thresholds: VIH = 1.4 V (minimum) and VIL = 0.45 V (maximum) when VCC = 3.0 V. This ensures reliable recognition of standard 5 V TTL outputs while operating from a 3 V rail - a key differentiator from CMOS-threshold variants like MC74VHC1G08.
Does MC74VHC1GT08DF1G support level shifting between 3 V and 5 V domains?
Yes. MC74VHC1GT08DF1G features over-voltage tolerant inputs and outputs rated to 5.5 V regardless of VCC. When powered from 3.0 V, it safely accepts 5 V logic signals on A or B inputs and drives 5 V-tolerant loads on Y - eliminating external level-shifting components in mixed-supply interfaces.
What package type is used for MC74VHC1GT08DF1G?
MC74VHC1GT08DF1G uses the SC-88A package (JEDEC MO-178, Case 419A), a 5-pin, 2.1 mm × 2.0 mm surface-mount outline with 0.65 mm lead pitch. Pin 1 is identified by a dot or bevel; marking includes "VT" code and date code per onsemi's standard SC-88A labeling convention.
Is MC74VHC1GT08DF1G suitable for automotive applications?
MC74VHC1GT08DF1G is the industrial-grade version. For automotive use, onsemi offers the −Q suffix variant (e.g., MC74VHC1GT08DFT1G−Q), which is AEC-Q100 qualified and PPAP capable. The base MC74VHC1GT08DF1G shares identical electrical specs and thermal ratings (−55 °C to +125 °C) but lacks automotive-specific qualification documentation.
What is the maximum propagation delay of MC74VHC1GT08DF1G across temperature?
At VCC = 4.5–5.5 V and CL = 15 pF, the maximum tPLH/tPHL for MC74VHC1GT08DF1G is 9.0 ns over −55 °C to +125 °C. At 3.0–3.6 V and same load, it is 12.5 ns. These values are guaranteed in the datasheet's AC Electrical Characteristics table and reflect worst-case performance under full industrial temperature stress.
