The IDT74ALVCHS162830DFG is a logic device that falls into the category of Buffers, Drivers, Receivers, Transceivers. It is used in an array of applications such as in the transmission of data, digital signals and digital processing. The product is a low power, reduced pin count device made specifically for integration into various systems.

The IDT74ALVCHS162830DFG consists of 16 buffer/drivers which are bidirectional. These buffers/drivers can convert between two different logic levels, such as 3V and 5V. Any one of the buffers can be enabled using the enable pin which can be used in both enable or disable logic levels. It is designed to drive lower capacitance loads than other similar buffers and can provide data rates of up to 160MHz. The device can also be used with multiplexer/demultiplexer (MUX/DEMUX) configurations.

In terms of its working principle, the IDT74ALVCHS162830DFG provides a low-voltage interface for implementing 5V logic functions in a system with a lower supply voltage. The device is enabled with a single latchable chip-enable (CE) and provides a low-voltage interface by buffering the output to a level closer to the supply voltage of the system. The device responds to the CE signal by latches and stores the current input data. The device will assumes the disabled state if the CE signal goes low. Once the CE signal goes high, the device latches the data on the data inputs and the output will match the inverted data on the data input pins.

The IDT74ALVCHS162830DFG is also capable of being used as a dual Vcc buffer which has two different Vcc connections, one for each half of the buffer. This can be used to interface different Vcc supplies in a single chip thus making it useful for interfacing signals from a low-power memory, to higher power logic. The buffer also features active pulldown networks on the output to reduce device power consumption by keeping outputs in the low state when not being used.
