STMicroelectronics 74V1G04CTR

Overview

74V1G04CTR from STMicroelectronics is a single high-speed CMOS inverter with 3.8 ns typical propagation delay at 5V, 2V–5.5V operating voltage range, ±8 mA symmetrical output drive, and input tolerance up to 7V independent of VCC. It enables level-shifting between 5V and 3V logic domains in compact portable and industrial control interfaces.

For engineers reviewing the 74V1G04CTR datasheet, 74V1G04CTR pinout, 74V1G04CTR application, or 74V1G04CTR equivalent, key selection criteria include its power-down protected inputs, 28% VCC noise immunity, sub-10 ns AC timing across temperature, and SOT323-5L package compatibility with space-constrained PCB layouts.

Technical Context

The device implements a three-stage buffered inverter architecture using sub-micron C2MOS technology, delivering balanced tPLH/tPHL delays and stable output under varying load and supply conditions. Its input stage accepts 0–7V regardless of VCC, enabling robust interfacing across mixed-voltage systems.

DC specifications guarantee VIH ≥ 0.7VCC and VIL ≤ 0.3VCC over full temperature range (–55°C to +125°C), while symmetrical |IOH| = |IOL| ≥ 8 mA at 4.5V ensures consistent rise/fall edge integrity for clock and data inversion tasks.

Key Specifications

Pinout & Package

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, designing and manufacturing microcontrollers, power management ICs, analog chips, and MEMS sensors for industrial, automotive, and consumer markets.

The 74V series targets high-speed, low-power logic applications where robustness, wide supply range, and mixed-voltage interoperability are critical-especially in harsh-environment control and instrumentation systems.

FAQ

Can 74V1G04CTR be used with a 1.8V supply?

No. The recommended minimum VCC is 2.0V per datasheet Section "Recommended Operating Conditions". At 1.8V, VIH and VIL thresholds fall outside guaranteed logic levels, risking unreliable switching and increased static current. Operation below 2V is not characterized or supported.

Is Pin 1 (NC) required to be tied to GND or left floating?

Pin 1 is internally unconnected and may be left floating. STMicroelectronics' mechanical drawings and application notes confirm no electrical function or thermal requirement exists for this terminal. Grounding it offers no benefit and risks unintended solder bridging in fine-pitch assembly.

Does 74V1G04CTR support hot-swap insertion while VCC is off?

Yes. Its power-down protected inputs allow input voltages from 0V to 7V even when VCC = 0V, preventing back-powering and latch-up. This is explicitly verified in the "Power Down Protection on Input" feature and absolute maximum ratings table (VI = –0.5V to +7.0V).

What is the maximum capacitive load CL for guaranteed 3.8 ns tPD?

The 3.8 ns typical propagation delay is specified at VCC = 5.0V ± 0.5V with CL = 15 pF (including jig and probe capacitance). At CL = 50 pF, tPD increases to 4.7 ns. Exceeding 50 pF degrades timing predictability and may violate setup/hold margins in synchronous systems.
