The MC74AC14/74ACT14 contains six logic inverters that accept standard CMOS input signals (signal levels for the MC74ACT14) and provide standard CMOS output levels. They convert slowly varying input signals into clearly defined, jitter-free output signals. Additionally, their noise margins are better than conventional inverters. The MC74AC14/74ACT14 has hysteresis (typically 1.0V) between the positive-going and negative-going input thresholds, which is determined internally by the transistor ratio and is essentially insensitive to temperature and supply voltage variations.

The NC7S32 is a high performance single 2-input CMOS OR gate. Advanced silicon-gate CMOS fabrication process ensures high-speed, low-power circuit operation over a wide range of VCC. ESD protection diodes are built-in to protect the VCC and GND rails of the input and output. Three stages of gain between input and output ensure high noise immunity and reduce sensitivity to input edge rates.

The LCX00 contains four 2-input NAND gates. The input allowable voltage is up to 7V, allowing the connection of 5V system to 3V system. The 74LCX00 is fabricated using advanced CMOS technology to achieve high-speed operation while maintaining CMOS low power consumption.

The NLSX4014 is a 4-bit configurable dual-supply bidirectional level shifter that does not require a direction control pin. The IO VCC and IO VL ports are used to track two different power rails, VCC and VL, respectively. The VCC rail is configurable from 1.3 V to 4.5 V, while the VL rail is configurable from 0.9 V to (VCC - 0.4) V. This allows lower voltage logic signals on the VL side to be converted to higher voltage logic signals on the VCC side and vice versa. Both I/O ports are auto-sensing, eliminating the need for direction pins. The output enable (EN) input, when low, places both I/O ports in 3-state, thereby disabling them. This greatly reduces supply current from VCC and VL. The EN signal is used to track VL.
