STMicroelectronics 74LVC00AMTR

Overview

74LVC00AMTR from STMicroelectronics is a low-voltage CMOS quad 2-input NAND gate with pin- and function-compatibility to 74-series 00 logic. It operates from 1.65 V to 3.6 V, delivers symmetrical 24 mA output drive at 3 V, achieves 4.3 ns max propagation delay, and supports 5 V-tolerant inputs for mixed-voltage interfacing in 3.3/5 V systems.

For engineers reviewing the 74LVC00AMTR datasheet, 74LVC00AMTR pinout, 74LVC00AMTR application, or 74LVC00AMTR equivalent, key selection criteria include its balanced tPLH/tPHL delays, power-down protection on all I/Os, latch-up immunity >500 mA, ESD robustness (HBM >2 kV), and guaranteed PCI bus levels at 24 mA drive.

Technical Context

The 74LVC00AMTR implements four independent NAND gates using sub-micron C2MOS technology, enabling high-speed operation with low static and dynamic power consumption. Its input structure includes clamping diodes and protection circuitry that ensure 5 V tolerance while operating from as low as 1.65 V supply.

Propagation delay symmetry (tPLH ≅ tPHL) and matched output impedance (|IOH| = IOL ≥24 mA at VCC = 3 V) support clean signal integrity in timing-critical combinatorial logic paths. The device maintains valid logic states across –55 °C to +125 °C and retains data down to 1.2 V.

FAQ

Can 74LVC00AMTR be used with a 5 V supply?

No - the absolute maximum VCC rating is +7.0 V, but the recommended operating range is strictly 1.65 V to 3.6 V. Applying 5 V to VCC exceeds specifications and risks permanent damage. However, inputs tolerate up to 5.5 V regardless of VCC, enabling safe interfacing with 5 V signals when powered at 3.3 V.

Does 74LVC00AMTR support hot insertion?

Yes - its power-down protection ensures inputs and outputs remain high-impedance and non-destructive when VCC = 0 V. This prevents back-driving of live buses and avoids damaging upstream components during live board replacement, satisfying hot-swap requirements in modular systems.

What is the significance of balanced tPLH and tPHL?

Matched propagation delays ensure equal rise and fall times across logic transitions, preserving pulse width integrity in feedback paths, clock dividers, and synchronous state machines. For the 74LVC00AMTR, tPLH ≅ tPHL minimizes duty-cycle distortion - critical in applications like oscillator circuits or PWM signal conditioning.

How does the 74LVC00AMTR differ from standard 74HC00?

Unlike 74HC00, which requires ≥2 V VCC and lacks 5 V input tolerance, the 74LVC00AMTR operates down to 1.65 V, guarantees 5 V-tolerant inputs, offers higher output drive (24 mA vs. 4 mA), and features lower ICC (10 µA vs. ~2 µA typical but unguaranteed). It also exceeds JESD17 latch-up limits by >5×.
