PI74FCT16244CTVE is a dual non-inverting 3-state buffer/line driver device from IDT. It is a member of the FCT family of low-skew, low voltage devices targeted for local bus or address routing applications. This device has two non-inverting buffer/drivers, each with a complemented output, plus two 3-state outputs with active-low output-enable inputs.

Applications

The PI74FCT16244CTVE is designed to be used in applications in which a low-skew and low-capacitance level shifting buffer is required. Examples of such applications include local and system buses, address routing, data multiplexing, data and address buffers, memory decoders, and address/data multiplexers.

Features

The PI74FCT16244CTVE features low power consumption (dynamic current of 2.25mA) and has a maximum propagation and output delay per output of 6.9ns. The device also has improved noise immunity and latch-up immunity. It is available in a 28-pin SOIC, VQFN, and SSOP package and can be supplied in the -I, -L, and -S speed grades.

Working Principle

The PI74FCT16244CTVE is a dual non-inverting 3-state buffer/line driver device. It has two non-inverting buffer/drivers, each with a complemented output, plus two 3-state outputs with active-low output-enable inputs. When the output-enable (OE) pin is inactive (high), the outputs are disabled and the device behaves as if all output terminals are connected to their respective active logic levels, whichever it may be. When OE is active (low), the outputs are enabled and the device allows data to be routed as normal. The 3-state outputs allow more than one device to be connected to a bus, while the complemented outputs allow data to be buffered on a single device.

Conclusion

The PI74FCT16244CTVE from IDT is a dual non-inverting 3-state buffer/line driver device suitable for use in applications where low-skew, low-capacitance level shifting is required. It offers low power consumption, improved noise immunity and latch-up immunity, and is available in a range of package options. The device allows data to be routed as normal when the output-enable is active and behaves as if all output terminals are connected to their respective active logic levels when the output-enable is inactive.
