Product Overview: 74VCXH1632245TBR from STMicroelectronics

The 74VCXH1632245TBR is a high-speed CMOS device from STMicroelectronics, designed to meet the demands of high-performance data communication systems. This product is part of the very low voltage range of interface devices that offer 1.65V to 3.6V power supply levels, making it ideal for interfacing with the next generation of microprocessors and microcontrollers in 3.3V systems.

With its 16-bit bus interface, the 74VCXH1632245TBR is perfect for those applications requiring a two-way asynchronous communication between data buses. The transmission of data from the A bus to the B bus or from the B bus to the A bus is determined by the level of the direction control (DIR) input. Meanwhile, the output enable (OE) input can disable the device so that the buses are effectively isolated.

The device offers a non-inverting buffer, providing a high degree of drive capability while maintaining low power dissipation. This is particularly useful in extending the battery life of portable devices when interfaced with the phone, tablet, or other low-power consumer electronics.

One of the key features of the 74VCXH1632245TBR is its bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors, saving board space and reducing component costs. The device also supports live insertion and withdrawal (partial-power-down mode) which means it can be inserted or removed without turning off the system power, a significant feature for server and network maintenance.

The 74VCXH1632245TBR is packaged in a TSSOP56 (Thin Shrink Small Outline Package), ensuring a compact footprint on the PCB, and it operates over the -40°C to +85°C temperature range. This, combined with the lead-free, halogen-free, and RoHS compliant construction, makes it an environmentally friendly choice for modern electronic designs.

In summary, the 74VCXH1632245TBR from STMicroelectronics is a robust, versatile, and efficient solution for high-speed data transfer in low-voltage applications, offering features that enhance system reliability, reduce power consumption, and simplify design complexity.
