onsemi MC74LVX00DT

Overview

MC74LVX00DT from ON Semiconductor is a quad 2-input NAND gate IC designed for level-shifting logic interfacing between 3.0 V and 5.0 V systems. It features 5 V-tolerant inputs (up to 7.0 V), 4.1 ns typical propagation delay at VCC = 3.3 V, ±25 mA output drive, and operates across −40°C to +85°C. It is used in mixed-voltage digital control subsystems requiring robust noise immunity and low-power CMOS compatibility.

For engineers reviewing the MC74LVX00DT datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance, propagation delay matching, output drive capability under 3.3 V supply, and TSSOP-14 package compatibility with high-density PCB layouts.

Technical Context

The MC74LVX00DT implements four independent 2-input NAND gates in a single monolithic CMOS structure. Its input stage incorporates protection circuitry enabling safe operation with 5.0 V signals while powered from a 2.0–3.6 V supply - critical for bridging legacy 5 V logic and modern low-voltage microcontrollers.

Each gate delivers balanced tPLH/tPHL propagation delays (≤9.7 ns max at VCC = 3.3 V, CL = 50 pF) and exhibits ≤1.5 ns output-to-output skew, ensuring deterministic timing in synchronous logic paths. The device supports 50 pF capacitive loads and maintains VOL ≤ 0.44 V at IOL = 4 mA, enabling reliable TTL-compatible low-level signaling.

FAQ

What is the maximum input voltage rating for MC74LVX00DT?

The MC74LVX00DT supports DC input voltages from −0.5 V to +7.0 V, independent of VCC. This 5 V-tolerant input capability allows direct connection to 5.0 V logic sources while operating from a 3.3 V supply - a key differentiator versus standard LVC-family devices. Absolute maximum ratings must not be exceeded during operation or power-up sequences.

Can MC74LVX00DT operate reliably at 2.0 V supply?

Yes, MC74LVX00DT is fully specified down to VCC = 2.0 V across the full temperature range (−40°C to +85°C). At 2.0 V, VIH is guaranteed ≥1.5 V and VOL ≤ 0.1 V at IOL = 50 µA, supporting ultra-low-power applications such as battery-operated remote sensors or energy-harvesting nodes where supply headroom is constrained.

Does MC74LVX00DT require external pull-up resistors on inputs?

No, MC74LVX00DT does not require external pull-ups. Its inputs have negligible leakage current (±0.1 µA max at VCC = 3.6 V), and internal structure provides defined logic states when left unconnected only in static conditions - however, best practice mandates explicit termination (pull-up or pull-down) in all production designs to prevent floating inputs, noise coupling, and increased ICC during transitions.

What is the thermal performance of MC74LVX00DT in TSSOP-14 package?

The MC74LVX00DT in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of 150°C/W (typical, still air). At maximum rated power dissipation (180 mW), this yields a worst-case junction temperature rise of ~27°C above ambient - well within safe operating limits for industrial applications. No heatsink is required under normal logic loading conditions.

Is MC74LVX00DT pin-compatible with standard 74-series NAND gates?

Yes, MC74LVX00DT is functionally and pinout-compatible with industry-standard quad 2-input NAND packages including 74HC00, 74HCT00, and 74LV00 in TSSOP-14. Pin assignments match Figure 1 of the datasheet: inputs and outputs follow identical 14-pin mapping, enabling drop-in replacement where 5 V input tolerance and low-voltage operation are needed - though voltage ratings and AC specs differ.
