SN74AVC20T245 20-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Output

The MC74VHC1GT126 is a single-gate non-inverting 3-state buffer fabricated using silicon-gate CMOS technology. It achieves high-speed operation similar to an equivalent bipolar Schottky TTL while maintaining CMOS low power consumption. The MC74VHC1GT126 requires the 3-state control input (OE(bar)) to be set low to place the output in a high impedance state. The device input is compatible with TTL-type input thresholds, and the output has a full CMOS level output swing. Input protection circuitry on the device allows overvoltage tolerance on the inputs, enabling the device to be used as a logic level translator from 3.0V CMOS logic to 5.0V CMOS logic, or 1.8V CMOS logic to 3.0V CMOS logic, and Capable of running on high voltage power supplies. The MC74VHC1GT126 input structure provides protection when voltages up to 5.5V are applied regardless of the supply voltage. This allows the MC74VHC1GT126 to be used as an interface to 5V to 3V circuits. The output structure also provides protection when VCC = 0V. These input and output structures help prevent device damage due to supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc.

The NC7SZ38 is a single 2-input NAND gate with open-drain output stage, part of ON Semiconductor's TinyLogic UltraSpeed ​​family. The device is fabricated using advanced CMOS technology to achieve ultra-high speed and high output drive while maintaining low static power consumption over a very wide VCC operating range. The device is specified to operate from a VCC range of 1.65 to 5.5V. When VCC is 0V, the input and output are high impedance. The input is tolerant to 6V independent of the VCC operating voltage. In the high-impedance state, the open-drain output stage withstands voltages up to 6V independent of VCC.

The VHCU04 is an advanced high speed CMOS inverter fabricated in silicon gate CMOS technology. It achieves high-speed operation similar to an equivalent bipolar Schottky TTL while maintaining the low power consumption of CMOS. Since its internal circuit consists of a single-stage inverter, it can be used in analog applications such as crystal oscillators. An input protection circuit ensures that 0V to 7V is applied to the input pins regardless of the supply voltage. The device can be used as an interface between 5V and 3V systems as well as two power systems such as battery backup. This circuit prevents damage to the device due to mismatched supply and input voltages.
