The 74FCT162827CTPVG8 is a Logic product that belongs to the family of Buffers, Drivers, Receivers, Transceivers. It is a high-speed, low-power, CMOS device featuring three independent buffer circuits. This device provides logic buffer inputs and output support on a 20-pin Vcc package, allowing for the use of small circuit boards with minimal trace routing. This device is suitable for use over ranges of +2.2 to 3.6 V.

Application Field

This device is primarily designed for optoelectronic and digital logic functions in communications, industrial, automotive and consumer applications. It is suitable for translation between digital logic and CMOS bus-oriented logic, as well as for various memory, EPROM and microprocessor/microcontroller applications. The inputs can be driven from either 5-V or 3.3-V logic, while all outputs are capable of driving up to 10 LSTTL loads. The outputs can also be used to drive 4 TN, Micronetics, STTL, and LSTTL logic, while the inputs can be used with all types of logic.

Working Principle

The 74FCT162827CTPVG8 includes three independent buffer circuits. The input and output metal-oxide semiconductor (MOS) transistors are controlled by the "DIN", "DOUT", and "EN" pin functions, respectively. When the EN pin is high, the three input pins (DIN) may be driven from either 5-V or 3.3-V logic, while all outputs are capable of driving up to 10 LSTTL loads. When the EN pin is low, the output pins are disabled, allowing the low power-saving both standby and active mode. The device is fabricated with advanced CMOS technology to reduce the total power consumption and to provide high speed operation with “Tri-State” outputs. The output pins are also in “High Impedance” state when the EN pin is low.

The outputs provide high noise-immunity and a short propagation delay. The input levels are compatible with all popular types of logic, ranging from TTL to ECL levels. Furthermore, the available chip also has open-drain operation with external pull-up resistor when connected to a logic circuit that drives the outputs from 1.65 V to 3.6 V. The EN, DIN and DOUT pins can also be independently programmed and the output states can be set up with the associated control signals.

The 74FCT162827CTPVG8 is designed to function over an ambient temperature range of -55°C to 125°C, and boasts a variety of features including a minimum supply voltage of 2.2V, an operating flux density of up to 2000 μT, high component density, and a standby power of less than 200μA. The device is especially suitable for those applications in extreme environments where space is a premium, such as embedded systems, automotive control and wireless communications.
