The SN74VMEH22501DGVR is a logic device specifically optimized for use with the VMEbus system in a variety of applications. The SN74VMEH22501DGVR is an 8-bit programmable logic device that provides universal bus functions for a variety of applications. The device contains 16 Logic Data Registers (LDRs) to latch data from input pins and 16 Logic Block Registers (LBRs) to enable their corresponding outputs. The device can be preprogrammed with a combination of 4 independent logic functions.

The SN74VMEH22501DGVR\'s main features include universal bus functions, programmable logic, multiple logic block operations (MBLOCs) and wide operating temperature range. The SN74VMEH22501DGVR also has programmable outputs drivers and can source/sink up to 5mA per output. Additionally, it has TTL and CMOS compatible inputs and outputs, a TTL compatible clock input and an integrated pull-up resistor.

The SN74VMEH22501DGVR is a programmable logic device that provides universal bus functions for a variety of applications. The LDRs and LBRs allow for programmable logic functions to be implemented that can be used in applications such as addressing, data transfer, bus arbitration, data signalling and many more. The MBLOC feature enables the implementation of multiple logic functions within the same block of code, allowing for complex abstraction level implementations such as multiplexers and programmable logic array (PLA).

The SN74VMEH22501DGVR has a wide operating temperature range that supports operation in extreme environments. It is designed to support a wide range of input and output voltage levels including high speed transition times and edge rates. Additionally, the SN74VMEH22501DGVR is designed to withstand electrical noise, vibration and shock that maybe experienced in the field.

The SN74VMEH22501DGVR works by receiving data from its input pins and passing it to one or more logic blocks, which are programmed with a combination of 4 independent logic functions. A logic block consists of 8 input logic elements (LEs) and 8 output logic elements (OE) that allow for complex logic operations. The logic block can be connected to as many LDRs and LBRs as required, which can be configured to receive and latch data from input pins, and enable outputs respectively. The outputs generated can either be switched on/off or be programmed to be active-low or active-high.

The SN74VMEH22501DGVR can be programmed using either the VMEbus-compatible programming language or using software tools. Once programmed, the SN74VMEH22501DGVR can provide universal bus functions for a variety of applications, such as coordination of system operations, data signalling, data transfer and addressing.
