STMicroelectronics 74LVQ00MTR

Overview

74LVQ00MTR from STMicroelectronics is a low-voltage CMOS quad 2-input NAND gate optimized for 3.3 V logic systems, featuring 5.5 ns typical propagation delay at V_CC = 3.3 V, ±12 mA symmetrical output drive, and 2 V to 3.6 V operating voltage range. It delivers low-noise operation (V_OLP = 0.3 V typ.), 75 Ω transmission line driving capability, and 2 kV ESD immunity - deployed in PCI bus interface circuits and low-power embedded control logic.

For engineers reviewing the 74LVQ00MTR datasheet, 74LVQ00MTR pinout, 74LVQ00MTR application, or 74LVQ00MTR equivalent, key selection criteria include guaranteed PCI bus level compliance at 24 mA, balanced t_PLH/t_PHL delays, symmetrical I_OH/I_OL, 2 µA max quiescent current, and SOP-14 pin-and-function compatibility with legacy 74-series NAND gates.

Technical Context

The 74LVQ00MTR implements four independent NAND gates using sub-micron C2MOS technology with three-stage buffered outputs, enabling high noise immunity and stable switching across temperature ranges from –55 °C to +125 °C. Its input structure guarantees TTL-compatible thresholds and supports 1.2 V data retention.

Dynamic performance is characterized by 0.5 ns typical output-to-output skew (t_OSLH/t_OSHL) and incident-wave switching on 75 Ω transmission lines. Input rise/fall time tolerance is specified up to 10 ns/V at V_CC = 3.0 V, supporting robust signal integrity in high-speed digital interfaces.

FAQ

Is the 74LVQ00MTR compatible with 5 V TTL inputs?

Yes - its VIH and VIL thresholds (2.0 V and 0.8 V respectively at V_CC = 3.0–3.6 V) meet TTL input compatibility requirements. Inputs tolerate up to V_CC + 0.5 V, allowing safe connection to 5 V signal sources when current-limited, though sustained 5 V input operation is outside recommended conditions.

What is the maximum output current per pin under continuous DC conditions?

The absolute maximum DC output current per pin is ±50 mA, but the guaranteed minimum drive strength is ±12 mA at V_CC = 3.0 V with VOL ≤ 0.44 V and VOH ≥ 2.48 V. For reliable long-term operation, ST recommends limiting steady-state current to ≤24 mA per output, aligned with PCI bus specifications.

Does the 74LVQ00MTR require external pull-up or pull-down resistors on unused inputs?

No - all inputs feature integrated protection diodes and high-impedance CMOS structure. Unused inputs must be tied to V_CC or GND to prevent floating states that cause increased ICC and potential oscillation; no external resistors are needed beyond this hard-wire connection.

Can the 74LVQ00MTR operate at 1.8 V supply?

No - the recommended operating V_CC range is 2.0 V to 3.6 V. At 1.8 V, the device may fail to meet VIH/VIL thresholds, propagation delay specs, or output drive strength. While data retention is guaranteed down to 1.2 V, functional operation is not supported below 2.0 V.
