ON Semiconductor 74LCX16501MTD: 18-Bit Universal Bus Transceiver with 3.6V Tolerant Inputs and Outputs

The 74LCX16501MTD from ON Semiconductor is a high-performance, CMOS 18-bit universal bus transceiver designed to facilitate bidirectional communication between data buses. This device is capable of driving heavily loaded buses with capacities of up to 15 LSTTL loads. The 74LCX16501MTD is particularly suitable for driving bus lines in memory and microprocessor bus extension applications.

One of the key features of the 74LCX16501MTD is its 5V tolerant inputs and outputs, which allow interfacing with 5V logic without the need for external components. This makes it a versatile choice for mixed-voltage systems. The device operates at a voltage range of 2.3V to 3.6V, providing low power consumption and compatibility with low voltage microprocessors and ASICs.

The 74LCX16501MTD offers multiple modes of operation, controlled by the direction and output enable inputs. When in the transmit mode, data from the A bus is transmitted to the B bus, and vice versa when in the receive mode. The output enable inputs can disable the device so that the buses are effectively isolated.

Another notable feature of this transceiver is its bus-hold data inputs, which eliminate the need for external pull-up resistors, saving board space and reducing component count. The device also includes power-off high impedance inputs and outputs, which support live insertion and withdrawal, minimizing device damage during hot swapping.

The packaging for the 74LCX16501MTD is a 56-Lead TSSOP, providing a compact footprint. This transceiver is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

With its robust design and advanced features, the ON Semiconductor 74LCX16501MTD is an excellent choice for designers looking to implement efficient data transfer in their digital systems, while maintaining compatibility with future technology upgrades.
