STMicroelectronics 74VHC04MTR

Overview

74VHC04MTR from STMicroelectronics is a high-speed CMOS hex inverter IC with 6 independent inverting buffers, operating from 2V to 5.5V supply, delivering 3.8ns typical propagation delay at 5V, ±8mA symmetrical output drive, and 2µA max quiescent current at 25°C - used for logic-level translation, clock buffering, and signal inversion in mixed-voltage digital systems.

For engineers reviewing the 74VHC04MTR datasheet, 74VHC04MTR pinout, 74VHC04MTR application, or 74VHC04MTR equivalent, key selection criteria include input voltage tolerance (0–7V), power-down input protection, ESD immunity (2kV), balanced tPLH/tPHL delays, and SO-14 package compatibility with legacy 74-series footprints.

Technical Context

The device implements six independent CMOS inverter stages using sub-micron C2MOS technology with buffered outputs, enabling high noise immunity (VNIH/VNIL ≥ 28% VCC) and stable switching across temperature (–55°C to +125°C). Input structure accepts 0–7V regardless of VCC, supporting 5V-to-3V interfacing without level shifters.

All inputs feature diode clamping and power-down protection; outputs provide symmetrical sourcing/sinking (≥8mA) with low dynamic noise (VOLP ≤ 0.8V at 5V/50pF). The internal three-stage design ensures consistent edge integrity and latch-up immunity per JEDEC standards.

Key Specifications

Pinout & Package

74VHC04MTR is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, compliant with JEDEC MS-012 and ECIA EIA-782. Pin 7 is GND, Pin 14 is VCC; all six inverters are arranged as input-output pairs (1A→1Y, 3A→2Y, ..., 13A→6Y).

FAQ

Can 74VHC04MTR safely interface a 5V microcontroller output to a 3.3V FPGA input?

Yes. Its inputs accept 0–7V regardless of VCC, so with VCC = 3.3V, a 5V input is clamped internally without damage. The output swings rail-to-rail (0V to 3.3V), matching the FPGA's VIH/VIL thresholds. No external components are needed, and the 2kV ESD rating protects against handling transients during integration.

Does 74VHC04MTR require external pull-up or pull-down resistors on unused inputs?

No. All inputs feature built-in power-down protection and high-impedance state when VCC = 0. When powered, unused inputs should be tied to VCC or GND to prevent floating nodes and unintended switching - but no external resistors are required for ESD or latch-up prevention due to integrated diode clamps and input hysteresis.

What is the maximum capacitive load this device can drive while maintaining specified tPD?

The datasheet specifies tPD values for CL = 15pF and CL = 50pF loads. At VCC = 5V, tPD remains within spec (≤6.5ns) up to 50pF. Driving >50pF increases propagation delay nonlinearly and may cause ringing; for loads >50pF, add a series resistor (10–33Ω) near the output to dampen reflections and maintain signal integrity.

Is 74VHC04MTR compatible with lead-free reflow soldering profiles?

Yes. The SO-14 package is RoHS-compliant and rated for peak reflow temperatures up to 260°C (per JEDEC J-STD-020). Its moisture sensitivity level (MSL) is 1 - unlimited floor life at ≤30°C/60% RH - allowing direct placement without baking, provided storage conditions are maintained per manufacturer guidelines.
