STMicroelectronics 74VHC00MTR

Overview

74VHC00MTR from STMicroelectronics is a quad 2-input NAND gate in high-speed CMOS technology, operating from 2V to 5.5V supply, with typical propagation delay of 3.7ns at 5V, symmetrical output drive (±8mA), and input tolerance up to 7V independent of VCC. It enables 5V-to-3V logic interfacing in compact consumer and industrial control systems.

For engineers reviewing the 74VHC00MTR datasheet, 74VHC00MTR pinout, 74VHC00MTR application, or 74VHC00MTR equivalent, key selection criteria include input overvoltage tolerance, rail-to-rail output swing under load, ESD immunity (2kV HBM), propagation delay matching across gates, and SOP-14 package compatibility with legacy 74-series footprints.

Technical Context

The device implements four independent NAND gates using sub-micron C2MOS process with three-stage buffered output architecture, delivering high noise immunity (VNIH/VNIL ≥ 28% VCC) and balanced tPLH/tPHL delays. Input protection allows 0–7V signal acceptance regardless of VCC level, enabling mixed-voltage domain interfacing without level shifters.

All inputs feature power-down protection and diode clamping; outputs support symmetrical sourcing/sinking (≥8mA) with low dynamic noise (VOLP ≤ 0.8V). The internal design ensures latch-up immunity per JEDEC JESD78 and meets 2kV HBM ESD rating across all pins.

FAQ

Can 74VHC00MTR be used with a 3.3V supply while accepting 5V input signals?

Yes. Its inputs tolerate −0.5V to +7.0V regardless of V_CC, enabling direct connection of 5V signals to a 3.3V-powered device without external level shifters or clamping diodes. This is confirmed in Absolute Maximum Ratings and Recommended Operating Conditions tables.

What is the maximum output current per pin, and is it symmetric?

Each output delivers ≥8mA sourcing (I_OH) and ≥8mA sinking (I_OL) at V_CC = 5V, with symmetrical impedance ensuring matched rise/fall times. This is specified in DC Electrical Characteristics Table 6 under VOH/VOL test conditions with defined load currents.

Does 74VHC00MTR require external pull-up or pull-down resistors on unused inputs?

No. Unused inputs may be tied directly to V_CC or GND. The device includes internal input protection and does not require external biasing; floating inputs are electrically unsafe and must be avoided per design guidelines in the datasheet's Application Information section.

Is the SOP-14 package of 74VHC00MTR compatible with standard 74-series footprints?

Yes. The SO-14 package (JEDEC MS-012AC) matches the 150mil width and 1.27mm pitch of legacy 7400-series SOIC packages, enabling drop-in replacement in existing PCB layouts designed for 74LS00 or 74HC00 in SOP-14 form factor.
