The 74FCT16244CTPAG is a high performance, low-power high-speed CMOS buffer / line driver for faster edge rates and broad voltage ranges (from 3.3V to 5.0V). It features hex buffers / drivers, each having six inputs and an output enable terminal that can be used to drive passive buses or as a single six-input edge trigger. This buffer is capable of transmitting data at speeds up to 200 MHz with a typical tPD of 8ns. It is designed to handle a wide variety of applications, including reset sequencing and clock distribution.

The 74FCT16244CTPAG is well suited for applications such as microprocessor, memory and peripheral interfacing, data communications and high-speed bus system. It is used to drive the TTL and CMOS logic families. The ‘FCT16244CTPAG’ buffer is operated in a high performance, low power supply current, fast switching, and non-inverting mode.

Working Principle

The 74FCT16244CTPAG is capable of operating at operating temperature range of 0°C to 70°C. It is compatible with 5 V logic, input noise levels of up to 10mV, and acceptance degradation up to 10ns. The ‘FCT16244CTPAG’ buffer is equipped with an enable input which controls the output data. When the enable input is high, the input data will be transmitted to the output, otherwise, the output will be high-impedance. With a power supply of 3.3V, the output logic level is VCC-0.2V and with a power supply of 5V, the output logic level is VCC-0.4V.

In order to make sure that the output signals are loaded asynchronously, the 74FCT16244CTPAG buffer will invert the output for positive clock pulses with respect to the enable pin. The output voltage swing of the buffer is equal to VCC-0.8V. In other words, the 74FCT16244CTPAG will transmit data at the highest speed of 200 MHz peak with a typical tPD of 8 ns. Moreover, it reduces power supply current in normal operation mode and ensure absolute minimum power dissipation in both power-down and power-up mode.

Application Field

The 74FCT16244CTPAG buffer is provides extremely fast and low power logic level conversion suitable for microprocessor, memory, and peripheral interfacing, data communications and high speed bus systems. The buffer is especially useful in high pin-count applications such as memory bus, clock and address lines, bidirectional signal lines, industry-standard bus signaling and FIFO systems. In addition, it can also be used for reset sequencing and clock distribution.

The buffer is capable of interfacing with asynchronous circuits such as DMA and I/O ports. Furthermore, the 74FCT16244CTPAG buffer is also suitable for portable communication device and embedded system applications, as it offers lower power consumption at higher speed. The buffer is available in a variety of packages, such as SOIC, SSOP, or VSOP, and can be used with standard logic levels or even lower logic levels.

In conclusion, the 74FCT16244CTPAG buffer is an ideal solution for high speed, low power, and low voltage operation. It is capable of transmitting data up to 200 MHz, with a typical tPD of 8ns and a power dissipation of 4mA/channel. It is especially suitable for high pin-count applications, such as memory bus, clock and address lines, bidirectional signal lines, industry-standard bus signaling and FIFO systems.
