STMicroelectronics 74LVQ00TTR

Overview

74LVQ00TTR from STMicroelectronics is a low-voltage CMOS quad 2-input NAND gate in TSSOP-14 package, operating from 2.0 V to 3.6 V, with 5.5 ns typical propagation delay at 3.3 V, 12 mA minimum output drive (|IOH| = IOL), and 2 µA max quiescent current - deployed in 3.3 V logic interface, PCI bus signaling, and noise-sensitive digital control subsystems.

For engineers reviewing the 74LVQ00TTR datasheet, 74LVQ00TTR pinout, 74LVQ00TTR application, or 74LVQ00TTR equivalent, key selection criteria include transmission-line driving capability (75 Ω), symmetrical output impedance, balanced tPLH/tPHL delays, ESD immunity (2 kV), and pin/function compatibility with standard 74-series 00 gates.

Technical Context

The device implements four independent NAND gates using sub-micron C2MOS technology with three-stage buffered outputs, enabling high noise immunity and stable switching. Input thresholds are guaranteed across 1.2 V–3.6 V, and dynamic input/output voltage levels (VIHD = 2.0 V, VILD = 0.8 V) support robust signal integrity on terminated lines.

It delivers PCI bus-level drive (24 mA) while maintaining low-noise operation (VOLP = 0.3 V typ.), and features symmetrical output sourcing/sinking (12 mA min at 3.0 V) with matched propagation delays (tPLH ≅ tPHL) and low skew (<1.0 ns) - critical for synchronous multi-gate timing alignment.

FAQ

Is the 74LVQ00TTR compatible with 5 V TTL inputs?

Yes - its inputs are TTL-compatible with guaranteed VIH ≥ 2.0 V and VIL ≤ 0.8 V across 2.0–3.6 V VCC, allowing direct connection to 5 V TTL outputs without level shifters. Input protection diodes clamp excess voltage, and the 2 kV HBM rating ensures reliability in mixed-voltage environments.

What is the maximum output current the 74LVQ00TTR can safely source or sink?

The device guarantees |IOH| = IOL ≥ 12 mA at VCC = 3.0 V and supports up to 24 mA for PCI bus compliance. Absolute maximum DC output current is ±50 mA, but sustained operation above 24 mA requires thermal derating and verification of junction temperature per SOA curves in the datasheet.

Does the 74LVQ00TTR require external decoupling capacitors?

Yes - STMicroelectronics recommends a 100 nF ceramic capacitor placed within 3 mm of the VCC and GND pins. This mitigates supply transients caused by simultaneous switching of multiple gates and maintains VOLP ≤ 0.8 V under dynamic load, especially critical in high-speed or noise-sensitive applications.

Can the 74LVQ00TTR operate at 1.8 V?

No - the recommended operating VCC range is strictly 2.0 V to 3.6 V. At 1.8 V, input thresholds and output drive fall outside specification, and functionality is not guaranteed. For 1.8 V systems, consider the SN74LVC00A or 74ALVC00 families instead.
