The 74LCX245BQX is a logic buffer/driver/receiver/transceiver designed for medium to high-speed applications. It operates from a 3.3-V or 5-V supply and is designed to support a data rate of up to 48Mbps. The device features a differential receiver and an open-drain driver, the 74LCX245BQX is ideal for applications such as the local bus, the high-speed peripheral bus, the point-to-point interconnect links, and the bus transceivers.

Application Field

The 74LCX245BQX is well suited for multiple applications, including local buses, high-speed peripheral buses, point-to-point interconnections, and bus transceivers. It is also suitable for systems that require LSTTL or LVTTL to 6V TTL or LVCMOS to 5V logic translation.

In system designs that require the use of a variety of different logic levels, the device is useful for interfacing between different logic families. It is suitable for Intel Pentium and AMD Athlon processors, as well as for bus transceivers used in communications and consumer applications.

The 74LCX245BQX can be used for data transmission over a wide range of data rates, from a few hundred kbps up to 48 Mbps. It is particularly useful for applications that require data transfer over short distances, such as in USB and IEEE1394 links.

Moreover, the device is well-suited for protocol conversion between different types of communications networks. It can be used to bridge between Serial ATA, gigabit Ethernet, USB 3.2, and other high-speed interfaces.

Working Principle

The 74LCX245BQX is an open-drain driver and differential receiver. The open-drain driver is able to provide the logic levels of up to 6 V, and the differential receiver is set with a hysteresis level of up to 4 V.

The device is capable of driving up to 8 differential lines with one supply. It is powered from either a 3.3 V or 5 V supply and requires only a single voltage for both the driver and receiver operation.

The 74LCX245BQX has a wide logic level range, making it suitable for both single-ended and differential logic applications. It also provides excellent noise immunity, low propagation delay, ESD protection up to 16 kV, and low power consumption.

The device is also available in several packages, such as thin quad flat pack (TQFP), micro, and flexible small outline packages (FSOP). The device is IO configured and can be used in multiple systems.

The 74LCX245BQX is a versatile and high-speed logic buffer/driver/receiver/transceiver that can be used for a variety of data rate applications. It can be used for a variety of logic level systems, including LSTTL, LVTTL, and 6V TTL, as well as for communication protocols like Serial ATA, USB 3.2, and gigabit Ethernet.
