STMicroelectronics 74LVC04AMTR

Overview

74LVC04AMTR from STMicroelectronics is a low-voltage CMOS hex inverter with six independent inverters in a single SO-14 package, operating from 1.65 V to 3.6 V supply. It delivers symmetrical output drive (±24 mA at V_CC = 3 V), 4.5 ns max propagation delay at 3 V, and 5V-tolerant inputs for mixed-voltage interfacing in 3.3/5 V systems.

For engineers reviewing the 74LVC04AMTR datasheet, 74LVC04AMTR pinout, 74LVC04AMTR application, or 74LVC04AMTR equivalent, key selection criteria include input voltage tolerance, output drive strength at low V_CC, propagation delay matching (t_PLH ≅ t_PHL), power-down protection, and PCI bus-level compliance at 24 mA.

Technical Context

The 74LVC04AMTR implements six unbuffered CMOS inverters using sub-micron C2MOS technology, enabling rail-to-rail output swing and balanced rise/fall times. Its input structure supports 5 V tolerance without external clamping, while output stages deliver matched |I_OH| = I_OL ≥ 24 mA at V_CC = 3.0–3.6 V and maintain functionality down to 1.65 V.

It features power-down protection on all I/O pins-ensuring high-impedance behavior when V_CC = 0 V-and meets JESD17 latch-up immunity (>500 mA) and MIL-STD-883 HBM ESD rating (>2000 V). Propagation skew between outputs is guaranteed ≤1 ns over full temperature range.

FAQ

Can 74LVC04AMTR operate reliably at 1.8 V supply?

Yes. The device is fully specified from 1.65 V to 3.6 V, including guaranteed VIH/VIL thresholds, VOL/VOH levels, and 4 mA output drive at 1.65 V. At 1.8 V, it delivers t_PD ≤ 9.5 ns (CL = 30 pF) and supports stable operation in ultra-low-power microcontroller subsystems.

Does 74LVC04AMTR require external pull-up resistors on inputs?

No. Its CMOS inputs have ±5 µA leakage (max) and defined VIH/VIL thresholds across the full V_CC range. Pull-ups are unnecessary unless floating-input prevention is required for system-level noise immunity-internal structure does not rely on external biasing.

What is the maximum capacitive load this inverter can drive?

The device is characterized up to 50 pF (t_PD spec at 3.0–3.6 V), but can reliably drive ≥100 pF with increased propagation delay (≤12.5 ns at 1.65–1.95 V). For loads >50 pF, verify setup/hold margins in timing-critical paths using actual board parasitics and worst-case V_CC/temperature.

Is 74LVC04AMTR pin-compatible with older 74HC04 devices?

Yes-pinout and logic function match the 74-series 04 family. However, 74LVC04AMTR operates at lower V_CC (1.65–3.6 V vs. 2–6 V), offers 5 V-tolerant inputs, and provides stronger drive at 3.3 V. Direct replacement is electrically valid if supply voltage and loading align with LVC specs.
