TCA4311D

TCA4311D is a low-power CMOS 8-bit bus buffer designed to ensure compatibility between TTL and CMOS technologies. It forces the outputs of CMOS and TTL devices to work together in a single system and also features low power consumption and high noise immunity. TCA4311D is part of the interface – signal buffers, repeaters, splitters and is available in a compact 14-pin DIP (dual in-line package) or 14-pin surface mount package.

The working principle of the TCA4311D is quite simple. It consists of an inverting buffer amplifier which amplifies the logic signal from a TTL input and sends it out to a CMOS output. This allows the TTL devices to directly control the CMOS devices, even though their logic levels greatly differ. In this way, the TCA4311D functions as a signal repeater that ensures compatibility between different types of integrated circuits.

The applications of TCA4311D mainly include level conversion, logic expansion and inversion, tri-state connection, and signal buffering. These application fields are divided in power, speed and interface. In power sector TCA4311D can be implemented to reduce power consumption, speed-wise, the TCA4311D is capable of operation up to 20MHz, and in interface, the TCA4311D is applicable to several applications in both data and address buses.

In terms of power, the TCA4311D has a low-power architecture, capable of operating with a power supply ranging from 3.0V to 5.5V. It is also able to handle wide range of input voltages from 1.6V to 5.5V. In addition, it features low power consumption in both high and low states. The maximum power consumption of the TCA4311D is only 1.3 mW which makes it suitable for use in low-power and portable electronic devices.
