Logic - Translators, Level Shifters

The SN74AVCH16T245VR is a translator and level shifter typically used for data line buffering and low voltage application. It is a low-power, 16-bit, bus-controlled buffer/driver on a single chip with a voltage range of 1.65V to 5.5V. It is a registered version of the SN74AVC16T245. Both the input and output ports have active high/low-enable inputs as well as an active high/low-direction control for bidirectional operations.

The SN74AVCH16T245VR’s high-voltage input/output levels cover a wide variety of logic families and provide a robust option for applications where standard logic levels are inadequate. The device can be used with many logic families from traditional CMOS logic to low-voltage logic families like LVTTL. The device is also well suited for low-voltage PCMCIA applications where multiple voltage referencing operations are needed for PCMCIA signaling.

In terms of its working principle, the SN74AVCH16T245VR has two separate amplification sections. The first is the initial driver stage and the second is the output stage. The data inputs are routed to the first amplification section via the internal set of transistors. These transistors produce the appropriate logic levels with respect to the current logic standard used. These logic levels are then transferred to the second amplification section, which controls the final output states.

The direction control input is an active high/low input which is used to select the direction of the data flow. If the direction control input is high, then the data flows from the input port to the output port. If the direction control input is low, then the data flows from the output port to the input port. The enable inputs are also active high/low inputs and are used to enable or disable the amplifier section. The data is transferred from one side of the amplifier to the other when the enable inputs are low.

The SN74AVCH16T245VR is an ideal device for applications that require data line buffering, low voltage conversion, and bi-directional data transfers. It is also suitable for applications requiring translation between multiple logic families. It can be used in many low-voltage applications like PCMCIA-compatible devices, as well as traditional logic interfacing applications. With its high voltage input/output levels, the SN74AVCH16T245VR provides a robust solution capable of interfacing with a wide variety of logic families.
