NXP 74ALVC162835ADGG: 18-Bit Universal Bus Driver with 3-State Outputs

The NXP 74ALVC162835ADGG is a high-performance, 18-bit universal bus driver that comes with 3-state outputs. Designed to operate at a voltage range of 2.3V to 3.6V, this device is part of the Advanced Low-Voltage CMOS (ALVC) family, which is known for its low power consumption and high-speed operation. The 74ALVC162835ADGG is particularly suitable for driving bus lines or buffer memory address registers in high-performance computing and telecommunication systems.

Featuring a 56-pin TSSOP (Thin Shrink Small Outline Package), the 74ALVC162835ADGG offers a compact footprint for densely packed PCBs. Its bus-hold data inputs eliminate the need for external pull-up or pull-down resistors, simplifying board design and reducing overall component count. The device also supports live insertion and withdrawal (partial-power-down) to facilitate ease of maintenance and upgrade without system power down, which is essential for mission-critical applications.

With a broad operating temperature range of -40°C to +85°C, the 74ALVC162835ADGG is robust and reliable for industrial applications. Its balanced output drive with current limiting resistors provides low electromagnetic interference (EMI), which is a crucial factor in today's sensitive electronic environments. Additionally, the device is characterized for output voltage conditions of 0.5V to 3.6V, adding to its versatility in interfacing with different logic levels.

The 74ALVC162835ADGG incorporates 18-bit universal bus drivers with 3-state outputs, which can be individually controlled. This enables the device to either drive active signals on the bus or remain in a high-impedance state to avoid bus contention. The use of a bus-hold feature on the data inputs allows the inputs to retain the last driven value, which helps in preventing floating inputs when no driving source is present.

Overall, the NXP 74ALVC162835ADGG is a feature-rich, high-speed bus driver that provides a reliable solution for high-speed data transfer and buffering in advanced digital systems. Its low voltage operation, coupled with power and space efficiency, makes it an excellent choice for modern electronic designs.
