Nexperia 18-Bit Non-Inverting TTL Bus Transceiver, CMOS Logic Family, Surface Mount, 20-Pin SOT-8020 Package 74LVC245ABZX

Nexperia 74LVC245ABZX is an 18-bit non-inverting TTL bus transceiver from the 74LVC245A series, based on CMOS logic family technology. It is designed to facilitate bidirectional data transfer with 3-state outputs and directional control using OE and DIR pins. The device operates over a wide supply voltage range of 1.2 V up to a maximum of 3.6 V, making it suitable for modern low-voltage digital systems.

The transceiver supports TTL input and output logic levels, ensuring compatibility with both 3.3 V and 5 V devices, which is ideal for systems requiring voltage translation and mixed voltage operation. The Schmitt-trigger action on all inputs enhances noise immunity and allows tolerance for slower input signals, improving overall signal integrity in various industrial and electronic applications.

Integrated IOFF circuitry prevents damaging backflow current during partial power down conditions by disabling outputs, making this device reliable for low-power and power-managed applications. The maximum propagation delay is 4.1 ns at a capacitive load, supporting high-speed switching requirements in digital circuits.

The compact 20-pin SOT-8020 surface mount package with a height of 480 μm and length of 2 mm allows for dense PCB layouts and efficient automated assembly lines. This product is RoHS compliant, meeting environmental safety standards.

Common applications include industrial electronics, digital communications, embedded systems, and any application requiring reliable bus transceiver functions with low power consumption and fast data transfer.

This bus transceiver features 18 channels with non-inverting polarity for reliable signal transmission. It incorporates 3-state outputs with an Output Enable (OE) for high impedance OFF-state control. The transceiver supports TTL input and output levels, enabling interoperability with mixed voltage logic systems.

Low power CMOS technology ensures efficient operation with power-down mode support through IOFF circuitry. Schmitt-trigger inputs provide tolerance to slower input rise and fall times, improving signal integrity. Offers maximum propagation delay time of 4.1ns at capacitive load.

Compact surface mount device suitable for automated assembly with a 20-pin SOT-8020 package type. Compliant with RoHS standards ensuring environmentally safe manufacturing processes. The device's height is 480µm and length is 2mm, ensuring minimal PCB space utilization.
